The case of a 39-year-old man with a perianal verrucose carcinoma of 12 years' duration is presented. After local resection the tumor recurred several times and spread to the rectum. An abdominoperineal resection revealed neither infiltration of deeper layers nor lymph-node metastasis. Five other cases of perianal verrucose carcinoma, only two of which were described in detail, have been reported. Probably other examples have been reported under the names of "perianal florid papillomatosis,"13,23 "giant condyloma acuminatum"26 and "condyloma acuminatum with malignant transformation."9,12,27
Solitary fibrous tumor of the pleura (SFTP) is a rare tumor. The prognosis is relatively good, but up to 20% of the cases are malignant. We presented a case of a large mass of the thorax, showing malignant poor prognosis features.
A 73-year-old male, former smoker, presented with a history of dry cough. Chest CT revealed a left bronchopulmonary mass (11 cm × 14 cm) extending from the costal pleura to the left hilum. Histopathologic examination of the transbronchial lung biopsy was consistent with SFTP. A left pneumonectomy was performed due to invasive nature of the lesion.
According to features associated to poor prognosis (lung tumor ≥ 10 cm, hipercellularity, abundant intratumor blood vessels and areas of necrosis), and in spite of proliferation index (Ki67+) <1%, the case was discussed in a multidisciplinary meeting, and was assumed to be malignant. At the present time, the patient is his fifth month after surgery, in tight follow up.
This case highlights a rare SFTP presenting bad prognosis features, that although completely resected should have long-term follow-up due to the high risk of recurrence.
An 18-year-old boy presented with a giant midline mass with 9 years of evolution. The tumor was excised, and reconstruction made with a customized sternum implant and a free latissimus dorsi muscle flap with skin graft. Histological analysis was compatible with low-grade fibromyxoid sarcoma (LGFMS).
Background:
Hemangioblastomas commonly occur in the posterior fossa and are typically attributed to sporadic or familial Von Hippel–Lindau disease. Spinal hemangioblastomas, found in 7–10% of patients, are usually located within the cord (i.e., intramedullary). Here, a 58-year-old male presented with a purely extradural hemangioblastoma involving a spinal root that was surgically excised.
Case Description:
A 58-year-old male was admitted with a progressive paraparesis and incomplete sensory deficit. The magnetic resonance imaging documented a solid dumbbell-shaped lesion that extended through the left T3-T4 foramen resulting in nerve root and spinal cord compression. Following arterial embolization and lesion excision by both neurosurgeons and thoracic surgeons, the patient’s deficits improved. The postoperative computed tomography scan documented complete tumor removal, and the neuropathology revealed a hemangioblastoma.
Conclusion:
Here, we describe a 58-year-old male with a purely extradural thoracic foraminal T3-T4 dumbbell-shaped hemangioblastoma successfully treated by both embolization and surgical excision.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
