UNASSIGNED: Lacrimal gland adenoid cystic carcinoma (LGACC) is characterized by a high rate of recurrence, perineural invasion, and propensity for distant metastasis, resulting in poor prognosis. This case report aimed to highlight the diagnostic and therapeutic challenges of LGACC, underscore the importance of resectioning the tumor as completely as possible for the first time, adhere to postoperative adjuvant therapy, and provide detailed insights into its surgical and diagnostic management that may not be extensively covered in large case series and meta-analyses.
UNASSIGNED: A 34-year-old man presented with progressive left eye proptosis for 4 months. Initial evaluation and imaging led to a high suspicion of LGACC, which was confirmed after an eye-sparing excision of the left orbital tumor. The patient declined to undergo postoperative radiotherapy, which was recommended after the surgery. Thus, despite surgical intervention, the patient experienced tumor recurrence 3 months post-surgery, leading to orbital exenteration. Pathological examination confirmed the presence of poorly differentiated LGACC.This time the patient underwent postoperative radiotherapy, as recommended. However, despite local control, the patient developed an intracranial metastasis within a year.
UNASSIGNED: LGACC presents significant diagnostic and therapeutic challenges owing to its insidious onset, lack of specific symptoms, and high potential for recurrence and metastasis. Thus, this case emphasizes the need for early diagnosis, aggressive treatment, and adherence to postoperative adjuvant therapy to improve patient outcomes. Future research should focus on understanding the pathogenesis of LGACC and on developing standardized diagnostic and treatment protocols to enhance patient prognosis and survival.

Olfactory neuroblastoma (ONB) is an uncommon malignant tumor and is usually treated by a multidisciplinary approach includes surgery, radiotherapy, and chemotherapy. A 62 years-old male had a tumor in the nasal cavity and diagnosed as ONB with Kadish A stage. Anterior skull base surgery was performed as radical treatment. Since the surgical margin was negative, no postoperative radiotherapy was administered. 14 years after the surgery, bilateral otitis media with effusion (OME) was occurred, we found the recurrence tumor at bilateral retropharyngeal lymph node (RPLN) which surrounded the internal carotid arteries. Since these were unresectable, we planned chemoradiotherapy which was 70Gy of intensity modulated radiotherapy combined with two courses of carboplatin and etoposide. The tumor volume was reduced and bilateral OME were improved. He has been alive for 3 years after salvage treatment. Although ONB has a relatively good prognosis, it is known to often cause cervical lymph node metastasis. Grades III and IV of Hyams classification are considered high risk. This case, initial tumor was limited in the nasal cavity and its clinical classification was early stage, but Hyams classification was grade III. In reference to this case, considering that RPLN metastasis are difficult to radically resect at the salvage surgery, including this area in postoperative radiotherapy was considered an option.

OBJECTIVE: To explore the application value of the self-management manual combined with the case management model in postoperative management of nasopharyngeal carcinoma after radiotherapy.
METHODS: Eighty-four patients with nasopharyngeal carcinoma admitted to Yingtan People\'s Hospital from May 2020 to April 2022 were retrospectively included in this study. They were divided into the experimental group (receiving self-management manual combined with case management mode scheme, n=42) and the control group (receiving continuous management after conventional nasopharyngeal carcinoma radiotherapy, n=42) according to mode differences. The cancer-related fatigue [Cancer Fatigue Scale (CFS)], comfort status [General Comfort Questionnaire (GCQ)], self-management efficacy [Chinese Strategies Used by People to Promote Health (C-SUPPH)], self-care ability (self-care ability measurement), pain score [Visual analogue scale (VAS)], and quality of life [European Organization for Research and Treatment of Cancer QLQ-C30 (EORTC QLQ-C30)] were compared between the two groups after 4 weeks of radiotherapy. The adverse reactions of the two groups were recorded. Combined with periodic review and follow-up records, the prognostic factors of the two groups of patients were analyzed.
RESULTS: After treatment, the scores of physical fatigue (12.83±1.10), emotional fatigue (9.78±1.32), cognitive fatigue (5.62±1.31), and total score of CFS (28.24±2.26) in the experimental group were 12.83±1.10. The control group physical fatigue (13.90±1.25) points, emotional fatigue (10.55±1.40) points, cognitive fatigue (6.80±1.75) points, and total CFS (31.33±2.59) points in both groups were lower than before treatment. The experimental group was lower than the control group (ALL P<0.05). The physiological, psychological, spiritual, socio-cultural, and environmental scores of the experimental group were higher than those of the control group (all P<0.05). The scores of health knowledge, self-care skills, self-care responsibility, and self-concept score of patients in the experimental group were higher than the control group (all P<0.05). After intervention, the VAS score of the experimental group was lower than that of the control group (P<0.05). After intervention, the EORTC QLQ-C30 score of both groups increased significantly as compared with pre-intervention. The score in the experimental group was significantly higher than that in the control group [(80.05±10.72) vs (68.11±12.10), P<0.05]. Postoperative (various) adverse reactions in the experimental group were lower than the control group (all P<0.05). The factors influencing the prognosis of nasopharyngeal carcinoma patients were age, tumor stage, and intervention mode by Cox model analysis (all P<0.05).
CONCLUSIONS: The self-management manual combined with the case management mode can alleviate cancer fatigue, improve postoperative self-management ability, self-care ability, and quality of life of patients with nasopharyngeal cancer radiotherapy, reduce the occurrence of adverse reactions and improve the prognosis of patients. It is worth promoting in clinical settings.

Myxofibrosarcoma is a malignant mesenchymal tumor and a fibroblastic sarcoma of the elderly. Myxofibrosarcoma can be low-grade or high-grade depending on the cell characteristics. Wide surgical resection with or without radiotherapy and chemotherapy is the basis of its treatment. Sometimes, tumor cells secrete insulin or insulin-like substances and cause hypoglycemia attacks. Here, we intend to demonstrate the role of early surgery to end hypoglycemia attacks and prevent recurrence and metastases. We also intend to show the insufficiency of tru-cut biopsy to distinguish between low- and high-grade myxofibrosarcoma. An 82-year-old male patient visited our clinic with a rapidly growing giant mass in the left retroscapular area and suffered from hypoglycemic attacks several times a day. After imaging and initial biopsy, the tumor grade was indeterminate on histopathological examination; hence, the mass was removed surgically. The pathological examination resulted in high-grade myxofibrosarcoma whereas the initial biopsy could not elaborate on the grade. The hypoglycemia attacks ceased after the surgery. Adjuvant local radiotherapy at a total dose of 60 Gy was administered in 30 fractions to the surgery area with no complications after the surgery. No new mass, recurrence, or hypoglycemia attack was detected in the three-year follow-up. In conclusion, hypoglycemia attacks may be a marker of malignant tumor presence and may be a clue at the beginning and in the follow-up period both for recurrence and the aggressiveness of the tumoral mass. Because a biopsy may show the diagnosis but not the grade of the tumor, early surgical intervention is needed.

Some head and neck cancer surgeons found that many patients with locally advanced head and neck squamous cell carcinoma (LA-HNSCC) without postoperative radiotherapy (PORT) also have a good prognosis. The purpose of this study was to determine the effect of PORT on survival in patients with LA-HNSCC.
A case-match cohort analysis was performed at two institutions on patients with LA-HNSCC. Patients who received surgery alone were case-matched 1: 1 with patients treated by surgery plus PORT based on pT, pN, tumor subsite etc. RESULTS: 114 patients were matched into 57 pairs, with a median follow-up period of 40.2 months. No difference in overall survival (OS, HR 0.88; 95% CI 0.50-1.58; P = 0.79) or disease-specific survival (DFS, 0.86; 95% CI 0.50-1.50; P = 0.76) was observed with no PORT.
PORT isn\'t necessary for patients with LA-HNSCC who are treated for the first time as long as the head and neck cancer surgeon adhere to appropriate surgical concepts. The indications of PORT for patients with LA-HNSCC need to be further discussed.

Keloids are laterally growing fibroproliferative skin disorders. Severe keloids spread widely, sometimes over joints, thus significantly limiting motor function. They are associated with recurrent, very painful draining infections. Here, we report a case of a giant keloid that was successfully treated by combination therapy comprising surgery (partial resection followed by local flap transposition) and subsequent radiotherapy and steroid-plaster therapy. The keloid was first noticed when the patient was 7 years old at the site of a Bacille Calmette-Guérin vaccination she had received on her left shoulder in infancy. The keloid grew rapidly and widely after adulthood. A malignant tumor was suspected at another hospital, but a biopsy at age 45 years indicated the lesion was a keloid. Later, the keloid grew from the shoulder onto the chest and back and over the anterior axilla. At age 62 years, the patient was referred to our hospital. Under general anesthesia, the keloid was partially resected and the wound was covered with a local flap. Postoperative radiotherapy was performed 1 week later. The residual keloid was treated for 18 months with steroid tape. At 18 months after surgery, no recurrence of the keloid was observed. The patient had no pain or movement restriction. She was extremely satisfied with the results and considered the treatment to have improved her quality of life. While a standard strategy for severe keloid remains to be established, combination therapy comprising surgery, postoperative radiotherapy, and steroid-plaster therapy that aims to reduce inflammation and skin tension may be an option.

Pigmented villonodular synovitis (PVNS) is a benign proliferative disorder of the synovium that usually involves joints, tendon sheaths, and bursae. It presents rarely, however, in the temporomandibular joints (TMJs). This paper reports a 59-year-old female patient with PVNS of the TMJ and its clinico-pathologic features are discussed. The patient was treated with surgery and postoperative radiotherapy (PORT). Follow-up was conducted, and there were no recurrences, metastases, skin changes or joint stiffness noted. The main treatment of PVNS is surgical resection. However, postoperative radiotherapy is important for local control of extensive tumors or positive margins. We conducted a literature review for postoperative radiotherapy case reports related to PVNS of the TMJ.

The purpose of this study was to determine the effect of postoperative radiotherapy (PORT) on recurrence and survival in patients with oral squamous cell carcinoma (OSCC) of intermediate recurrence risk.
Intermediate risk patients, defined as pT1, pT2, pN0, or pN1 with at least one adverse pathological feature (eg, lymphovascular/perineural invasion), were identified from the head and neck databases of the Liverpool Head and Neck Cancer Unit and the Sydney Head and Neck Cancer Institute. Patients who received surgery and PORT were case matched with patients treated by surgery alone based on pN, pT, margins, and pathological features.
Ninety patients were matched into 45 pairs. There was significant improvement (P = .039) in locoregional control with PORT (84%) compared with surgery alone (60%), which was concentrated in the pN1 subgroup (P = .036), but not the pN0 subgroup (P = .331).
PORT significantly improves locoregional control for intermediate risk OSCC.

Primary angiosarcoma is a rare disease with a poor prognosis. It most commonly arises in the head and neck region; localization in the deep soft tissue of the neck is extremely rare. We herein present a case of angiosarcoma derived from the right internal jugular vein. A 79-year-old man presented with a 1-month history of a growing right neck mass. Computed tomography, magnetic resonance imaging, positron emission tomography-computed tomography, and fine-needle aspiration cytology revealed a malignant tumor of unknown origin. Right neck dissection was performed for both diagnosis and therapy. Immunostaining of the resected tumor cells revealed positivity for CD31, CD34, factor VIII-related antigen, and D2-40, which allowed for a definitive diagnosis of angiosarcoma. Postoperative radiotherapy (66Gy) was performed on the right neck, including the surgical bed and upper mediastinum. The patient was followed up for 10 months with no recurrence. Only six cases of angiosarcoma arising in the deep soft tissue of the neck have been reported in the English-language literature. The present report is the first to describe angiosarcoma arising from the internal jugular vein.

A whistle deformity is defined as a deficiency in the vertical length of the lip so that the free margins of the upper and lower lips do not meet normally, giving the appearance of whistling. This is a common secondary deformity of the vermilion in patients with cleft lip. A case involving a 61-year-old man who developed a whistle deformity as a result of two wedge resections and postoperative radiotherapy for treatment of squamous cell carcinoma of the lower lip is presented. Hyaluronic acid-based tissue filler and autologous microfat transplantation to the lower lip were used for definitive management of the patient\'s whistle deformity. After one year of follow-up, the patient was pleased with the overall result and noted marked improvement of his oral competence and overall appearance of the lip. The present case demonstrates that microfat transplantation is a viable option for correcting a whistle deformity, not only after surgery, but also following adjuvant radiotherapy - both of which potentially reduce graft viability secondary to decreased vascularity of the recipient site.
