BACKGROUND: Interdigital melanoma, as a subtype of acral lentiginous melanoma, is relatively uncommon in the Caucasian population. It frequently goes unrecognized for a prolonged period of time prior to diagnosis, due to its asymptomatic nature and variable clinical appearance. METHODS: We report the case of a 67-year-old Caucasian woman who presented with interdigital malignant melanoma affecting two neighboring interdigital spaces. It had evolved over a period of more than 15 years and had been initially misdiagnosed as tinea pedis due to the macerated appearance of the lesion and a positive mycologic examination...

Jennifer M Boland, Andrew L Folpe
Hemosiderotic fibrolipomatous tumor is an unusual, distinctive soft tissue neoplasm with locally recurring potential, which most commonly occurs in the ankle and foot. Morphologic evidence strongly suggests that hemosiderotic fibrolipomatous tumor is related to another rare, locally aggressive tumor of the distal extremities, pleomorphic hyalinizing angiectatic tumor, with areas identical to hemosiderotic fibrolipomatous tumor seen at the periphery in most if not all pleomorphic hyalinizing angiectatic tumor...

INTRODUCTION: Laminectomy is the traditional approach for posterior exposure of the spinal canal for tumor resection. Another technique is split laminotomy, which entails the division and retraction of the spinous processes and laminae to access the thecal sac. This technique has been employed for small-segment exposures, but not extensively explored for long-segment exposures. CASE: A 2-month-old male presented with progressive right-leg plegia. MRI of the spine revealed a large, intramedullary spinal-cord lipoma extending from C6 to L5...

The authors present a distinctive perineurioma (PN) variant which morphologically strongly resembles monophasic fibrous synovial sarcoma (MSS). The patients were 3 males and 1 female. The age ranged from 15 to 61years (mean: 44years). Locations included the sole, lower jaw, palm and foot. The tumor size ranged from 1.3cm to 2.5cm in the largest dimension (mean 1.8cm). Morphologically, all tumors had an identical, monotonous appearance. The perineurial cells were closely packed and created a confluent cellular whorls and/or sheets in a scarce stroma, with only focally discernible long, slender cytoplasmic processes typical for perineurial differentiation...

Infantile fibrosarcoma is a non-rhabdomyosarcoma soft-tissue sarcoma that occurs in infancy and which has a relatively good prognosis. A vincristine and dactinomycin (VA) regimen has been shown to be effective, although the duration of chemotherapy has not been well defined. We describe the case of a 4-month-old boy with a mass at the left dorsum of the foot who was diagnosed with infantile fibrosarcoma after resection of the tumor, the margin of which was macroscopically positive. VA treatment was carried out with careful monitoring of response and adverse effects...

Glomus tumors are hamartomas, which tend to occur in sites rich in glomus bodies, such as the subungual regions of digits or the deep dermis of the palm, wrist, forearm, and foot. Very rarely, they may involve peripheral nerves. We describe a patient, who, following surgical resection of a solitary glomus tumor of the left distal sciatic nerve in his teens, had recurrence with development of multiple tumors in the course of the nerve over several years. To our knowledge, this is the only known case of glomangiomatosis involving a major peripheral nerve...
