Bizarre parosteal osteochondromatous proliferation (BPOP), also termed Nora lesion, is a rare, benign tumor most often located in the hands and feet. We herein present the second reported case of BPOP affecting the spine, an uncommon location. One year after surgical excision, the patient was pain-free and showed no evidence of recurrence. We reviewed a total of 323 cases of BPOP among 101 articles, providing the first systematic update on the latest knowledge of BPOP. The age of patients with BPOP ranges from 3 months to 87 years, peaking in the second and third decades of life. The hands are the most common location of BPOP (58.39%), followed by the feet (20.81%). Imaging features play a key role in the diagnosis of BPOP, but histopathologic diagnosis remains the gold standard. Differential diagnosis of BPOP should be based on the epidemiologic and clinical features as well as clinical examination findings. Surgical resection is the most extensively used treatment for BPOP. Recurrence is common (37.44%) and can be treated with re-excision. This article can deepen our understanding of BPOP and will be helpful for the diagnosis and treatment of BPOP in clinical practice.

Pelvic masses frequently originate from the pelvic cavity and are often associated with uterine, ovarian, or intestinal disorders. This report describes the case of a patient with a pelvic mass diagnosed as a retroperitoneal dermoid cyst at our hospital. We analyzed this case and conducted a literature review, to mitigate the risk of misdiagnosis and enhance the treatment of retroperitoneal masses.

In dermatology, a keloid is one of the most common skin morphological abnormalities caused by excessive proliferation of fibroblasts. Keloids that are large or occur near important joint sites often cause varying degrees of physiological dysfunction in patients, therefore requiring medical treatment. A boy with congenital syndactyly developed huge keloids at the surgical site after undergoing surgical correction treatment. After treatment using trepanation combined with superficial radiotherapy (SRT-100) in our hospital, most of the boy\'s keloids shrank and flattened. The affected foot returned to its normal appearance, and the boy could wear shoes normally. The boy did not complain of pain, numbness, or any other distinctive discomfort after completing the treatment. This suggested that the combination of trepanation and SRT-100 may be one of the options for treating hypertrophic keloids that cannot be treated by surgical excision.

OBJECTIVE: Oral mucoceles are most frequently encountered on the lower lip. A variety of treatment options are currently employed, including surgical excision, pharmacological injections, and laser therapy. However, each of these approaches may introduce risks and potential complications. Clinical practice has demonstrated a potential for self-healing in lower lip mucoceles, making a conservative observational approach more appealing. This research is a prospective study aimed at evaluating the self-healing capacity of lower lip mucoceles.
METHODS: In this prospective study, patients with mucoceles were encouraged to intentionally delay medical intervention and to wait for self-healing. Disappearance of the mucocele for at least 3 months was defined as self-healing.
RESULTS: Thirty patients with lower lip mucoceles were included. With no intervention, 24 patients (80%) reported self-healing of lower lip mucoceles. The mean natural duration of the mucoceles was 3.63 (± 4.7; 1-24) months. After self-healing of the mucocele, the patients were followed up for 17.21 (± 9.45; 2-30) months and there were no reported recurrences.
CONCLUSIONS: Lower lip mucoceles have a high potential for self-healing and patients may be routinely encouraged to wait for self-healing.
CONCLUSIONS: The high self-healing rate observed in this study suggests that a conservative, non-interventional approach might be considered as the first-line management for lower lip mucoceles.

UNASSIGNED: Sebaceous gland hyperplasia of the eyelids, known as adenomatoid or pseudoadenomatous hyperplasia, is a rare benign condition. Optimal management strategies for this specific type of eyelid tumor require further investigation.
UNASSIGNED: The patient presented with a 21-year history of a progressively enlarged mass in the right lower eyelid. Previous treatments, including laser photocoagulation and surgical excision, have failed to prevent recurrence. The mass, characterized by a firm texture and low mobility, has raised concerns regarding malignancy. However, histopathological examination following surgical excision identified the mass as sebaceous gland hyperplasia. The patient\'s medical history was notable for benign gastrointestinal and intestinal polyps with no evidence of malignancy.
UNASSIGNED: A final diagnosis of eyelid sebaceous gland hyperplasia was established after surgical excision and comprehensive histopathological analyses. The patient\'s successful recovery without recurrence over a three-month follow-up period post-surgery highlights the efficacy of the surgical approach and the use of intraoperative frozen section pathological examination.

The combined approach of surgical resection along with superficial x-ray radiotherapy emerges as a superior treatment option for individuals with keloids, which hold huge potential for enhancing aesthetic outcomes and preventing keloid recurrence.

BACKGROUND: Cystic lymphangioma is a rare benign tumor that affects the lymphatic system. Mesenteric lymphangiomas in the small bowel are extremely uncommon.
METHODS: We present a 21-year-old female patient who complained of abdominal pain. The diagnosis of ovarian torsion was suspected after abdominopelvic unenhanced computed tomography and ultrasound revealed a large cyst in contact with the bladder, ovary, and uterus. The patient underwent emergency laparotomy performed by gynecologists, but it was discovered that the cystic tumor originated from the jejunum. Gastrointestinal surgeons were then called in to perform a cystectomy. Pathological examination confirmed the diagnosis of cystic lymphangioma of the mesentery. The patient had an uneventful postoperative recovery.
CONCLUSIONS: Mesenteric lymphangiomas can cause abdominal pain, and imaging techniques can help determine their characteristics, location, and size. Complete surgical excision and pathological examination are considered the standard treatment and diagnostic method.

This meta-analysis aims to evaluate and compare the effect of surgical excision followed by adjuvant radiotherapy and laser combined with steroids on keloids. Relevant studies reporting the recurrence rate or incidence of adverse events (AEs) were retrieved from the PubMed, Web of Science, Embase and Cochrane Library databases through August 2023. The quality of noncomparative single-arm clinical trials was evaluated using the methodological index for nonrandomised studies (MINORS) Methodological items. This meta-analysis was conducted utilizing Stata 12.0 statistical software. 26 studies involving 989 patients were included in the analysis. The recurrence rate in the laser combined with steroids therapy group (12.2%, 95% confidence interval [CI]: 5.9%-18.5%) was lower than that of the surgical excision combined with radiotherapy group (13.5%, 95% CI: 6.6%-22.2%). For the incidence of AEs, relatively low incidence of atrophy (0.0%, 95% CI: 0.0%-1.2%), telangiectasia (3.2%, 95% CI: 0.4%-7.6%), erythema (2.3%, 95% CI: 0.0%-10.6%), infection (0.2%, 95% CI: 0.0%-1.6%) and high hyperpigmentation rate (8.3%, 95% CI: 4.2%-13.4%) were obtained in the surgical excision combined with radiotherapy group. Compared with surgical resection followed by radiotherapy, the combination of laser and steroids for keloids showed a lower hyperpigmentation rate (6.5%), as well as a higher incidence of atrophy (22.7%), telangiectasia (6.4%), erythema (3.3%) and infection (3.3%). Only a hypopigmentation rate of 2.9% was obtained in patients treated with surgical excision plus radiotherapy. Current evidence revealed that surgical excision followed by adjuvant radiotherapy and laser combined with steroids therapy were effective and safe treatments for keloids, with relatively low recurrence rate and complication rate. Comparative studies are needed to further compare the effects of these two combination therapies on keloids.
