UNASSIGNED: Bleomycin is a glycopeptide antibiotic with outstanding anti-tumor effects. A major adverse effect of bleomycin is lung fibrosis. However, the development of cataracts as a severe adverse effect has not been reported.
UNASSIGNED: Herein, we describe the first case of cataract induced by bleomycin therapy in a 22-year-old male with testicular cancer. After surgical intervention and following five successive chemotherapy cycles of the BEP regimen, including bleomycin, etoposide and cisplatin, the patient reported a gradual painless loss of vision, with substantial decline in visual ability, especially in the right eye. Following comprehensive eye examinations, a cataract was diagnosed. Eventually, the patient underwent phacoemulsification and received replacement of the intraocular lenses.
UNASSIGNED: Bleomycin can cause cataracts, which induces a significant loss of vision. Therefore, clinicians should observe early symptoms and properly adjust treatment to prevent aggravation of symptoms.

BACKGROUND: Trophoblastic neoplasms are often associated with pregnancy, and nongestational trophoblastic neoplasms are extremely rare. Nongestational ovarian choriocarcinoma (NGCO) is a highly aggressive germ cell-derived tumor frequently presenting with early hematogenous metastasis.
METHODS: Herein, we report a case of a 28-year-old unmarried woman with regular menstruation who experienced vaginal bleeding 1 week after her last menstrual cycle. Doppler ultrasound revealed bilateral adnexal masses and elevated serum human chorionic gonadotropin (hCG) levels. The patient was initially misdiagnosed as presenting an ectopic pregnancy.
METHODS: The final pathology confirmed an International Federation of Gynecology and Obstetrics stage IA NGCO with bilateral mature teratoma of the ovary. This is an extraordinary instance of ovarian choriocarcinoma which emerged without any prior gestation, and the patient\'s lack of a history of pregnancy made the diagnosis ignored.
METHODS: After initial surgery and 1 cycle of bleomycin, etoposide, and cisplatin (BEP) chemotherapy, a laparoscopic fertility-preserving comprehensive staging surgery was performed. Two cycles of chemotherapy with BEP were administered as supplemental therapy postsurgery, and leuprorelin was administered to protect ovarian function.
RESULTS: Menstruation resumed 4 months after chemotherapy completion, and tumor indicators were within the normal range. No signs of recurrence were observed at the 36-month follow-up.
CONCLUSIONS: NGCO should be considered if a female patient exhibits irregular vaginal bleeding and masses in the adnexal area. The present case and our literature review also highlighted that fertility-sparing surgery and multidrug chemotherapy are effective methods for treating NGCO.

(1) Background: this case series and literature review aims to evaluate the efficacy and safety of electrochemotherapy in the management of aggressive spinal hemangiomas, presenting two distinct cases. (2) Methods: we present two cases of spinal aggressive hemangioma which were refractory to conventional treatments and underwent electrochemotherapy. Case 1 involves a 50-year-old female who presented with an aggressive spinal hemangioma of L1, who previously underwent various treatments including surgery, radio-chemotherapy, and arterial embolization. Case 2 describes a 16-year-old female with a T12 vertebral hemangioma, previously treated with surgery and stabilization, who faced limitations in treatment options due to her young age and the location of the hemangioma. (3) Results: in Case 1, electrochemotherapy with bleomycin was administered following the failure of previous treatments and resulted in the reduction of the lesion size and improvement in clinical symptoms. In Case 2, electrochemotherapy was chosen due to the risks associated with other treatments and was completed without any adverse events. Both cases demonstrated the potential of electrochemotherapy as a viable treatment option for spinal hemangiomas, especially in complex or recurrent cases. (4) Conclusions: electrochemotherapy with bleomycin is a promising treatment for aggressive spinal hemangiomas when conventional therapies are not feasible or have failed. Further research is needed to establish definitive protocols and long-term outcomes of electrochemotherapy in spinal hemangioma management.

BACKGROUND: Langerhans cell sarcoma (LCS) is a very rare malignant tumor of Langerhans cells that may metastasize to many organs. The diagnosis of this tumor is difficult and its prognosis is poor.
OBJECTIVE: To report the difficulty to diagnose LCS, and discuss therapeutic management of this rare entity.
METHODS: We report a case of LCS in a 52-year-old man who presented with an axillar lymphadenopathy. The diagnosis of nodular sclerosis type Hodgkin\'s disease was established after histologic examination. The patient was treated with chemotherapy (ABVD regimen: Doxorubicin, Bleomycin, Vinblastine, Dacarbazine) and radiotherapy with a partial response. However, disease recurrence was observed and histological analysis confirmed the diagnosis of Langerhans cell sarcoma. A revision of the initial histological examination concluded to the diagnosis of sarcoma from the beginning. We chose the ESHAP (Etoposide, Methylprednisolone, Aracytine, Cisplatin) regimen and clinical improvement of LCS was obtained after 2 cycles but the patient had a fatal outcome and died by disease progression.
CONCLUSIONS: Because of its rarity, diagnosis is difficult and an optimal treatment strategy for this disease has not yet been identified. Polychemotherapy can be an effective modality for the treatment of LCS.

The phenomenon of multiple external cervical root resorption (ECRR) lesions in a single patient is rare but may have a link with the chemotherapeutic agent bleomycin. This case details an adult male with multiple ECRR lesions that developed following chemotherapy. His treatment regimen for Hodgkin\'s lymphoma included the chemotherapeutic antibiotic bleomycin, which has previously been linked with development of multiple ECRR lesions. The patient developed graft versus host disease following an allogeneic stem cell transplant, which could have a significant role in the development and promotion of the ECRR lesions. In total, 8 teeth developed ECRR, and all the known causative factors were excluded when examined. To our knowledge, this is only the second reported case in the literature to link bleomycin to multiple ECRR lesions. This case report aims to bring the reader\'s attention to the fact that multiple cervical resorption lesions can develop simultaneously. These lesions can be difficult to diagnose and treat and are often misdiagnosed as caries. Finally, the reader should consider the possible role of bleomycin and graft versus host disease in development of multiple lesions of ECRR.

UNASSIGNED: Kaposiform hemangioendothelioma (KHE) is a rare and invasive vascular tumor that mainly occurs in children and is rarely seen in adults. We report a case of KHE found on the eyelid of an adult patient.
UNASSIGNED: We present an adult patient in whom KHE recurred 6 months after tumor resection. He underwent second surgical resection and intraoperative chemotherapy. There was no evidence of recurrence at the 3-year follow-up.
UNASSIGNED: KHE in adults is easy to be misdiagnosed. KHE can be treated by surgical resection. Complete resection of the tumor and intraoperative chemotherapy may help prevent a recurrence.

BACKGROUND: Brooke-Spiegler syndrome is a rare autosomal dominant disorder characterized by the continuous development of multiple benign skin appendage tumors. It is treated usually by repeated standard surgery. Here, we present a case study where electrochemotherapy (ECT) with bleomycin was used as an effective alternative approach in treating advanced dermal cylindromatosis of the head and neck in a patient with Brooke-Spiegler syndrome.
METHODS: A 45-year-old woman presented with multiple recurrent dermal cylindroma lesions on her scalp. Previous treatment consisted of several surgical excisions that resulted in psychological deterioration due to the formation of numerous scars and extensive alopecic areas. ECT was offered to provide tumor removal and disease control and to improve the patient\'s quality of life.
RESULTS: The treatment was well tolerated, and a significant reduction in neoplastic tissue was achieved. Importantly, scalp skin condition significantly improved, regaining a fair follicular density on the margins.
CONCLUSIONS: This report suggests the feasibility of bleomycin ECT as a less invasive alternative option for controlling multiple scalp cylindroma lesions with cosmetically acceptable results, and improving quality of life.

OBJECTIVE: To discuss the clinical diagnosis and treatment of extragonadal germ cell tumor.
METHODS: We analyzed the clinical data on a case of extragonadal germ cell tumor diagnosed and treated in the General Hospital of Eastern Theater Command and reviewed the relevant literature.
RESULTS: The patient was initially diagnosed with retroperitoneal tumor and treated by resection of the tumor together with the left kidney due to the large volume of the tumor, which was complicated by pancreatic injury. Postoperative pathology showed it to be extragonadal germ cell malignancy. Postoperative examination revealed space-occupying lesion in the left testis, with serum alpha fetoprotein (AFP), human chorionicgonadotropin (hCG) and lactate dehydrogenase (LDH) negative, followed by stage-two resection of the left testis, which was pathologically shown with testicular seminoma. The patient received 7 courses of cisplatin, etoposide bleomycin (PEB) regimen and was followed up for 8 years, which found no recurrence or metastasis, and the patient fathered no child during the postoperative follow-up.
CONCLUSIONS: For patients with a history of cryptorchidism and tumors located in the central axis, special attention should be paid to physical examination of the testes, testicular ultrasonography, and determination of AFP and other indicators to identify gonadal tumor metastasis. And if so, radiotherapy and chemotherapy can be considered first to reduce surgical complications and achieve accurate management.

A 23-year-old male was aware of pain around his left hip joint and visited a nearby orthopedic clinic. Swelling of the right testis was pointed out, and a testicular tumor was suspected. He was referred to the urology department of a local hospital. Blood analysis showed an increase of α-fetoprotein (AFP) (3,620 ng/ml). Computed tomographic (CT) -scan revealed a left iliac bone metastasis and morbid fracture. Right radical inguinal orchiectomy was performed. The pathological examination revealed mixed germ cell tumor (embryonic carcinoma and immature teratoma: 70%, seminoma: 30%). The diagnosis was non-seminomatous germ cell tumor, stage IIIc, and poor risk on the International Germ Cell Consensus Classification. After one cycle of a bleomycin, etoposide and cisplatinum (BEP) regimen, he was referred to our hospital. After a total of 4 cycles of BEP, AFP was normalized. Denosumab was also administered monthly. The CT-scan showed a reduction of bone metastasis and recovery of ossification. Bone biopsy did not show viable tumor cells. Because extirpation of the remaining mass would require resection of the left part of the pelvic bone with significant functional loss of the left limb, we performed close follow-up after an additional 2 courses of the etoposide and cisplatin regimen. The patient is currently alive without recurrence at 45 months after the last systemic chemotherapy.

Sclerotherapy with bleomycin can cause cosmetic complications, including flagellate dermatitis and hyperpigmentation, induced or exacerbated by microtrauma to the skin. We report a case of a 9-year-old pediatric patient with congenital vascular malformations in which a cohesive bandage (eg, 3M Coban) was utilized to prevent bleomycin-induced hyperpigmentation. Postoperatively and on follow-up, there were no signs of hyperpigmentation or dermatitis in our patient. This report highlights using skin protective measures during bleomycin sclerotherapy for improved postoperative outcomes. If a patient is undergoing bleomycin sclerotherapy, consider removing adhesive where possible and using cohesive bandage to secure lines, airway instruments, and monitoring equipment.
