Abstract

Superficial acral angiomyxoma (SA) that is digital angiomyxoma is a rare tumor with a predilection for the subungual or periungual regions of the hands and feet. To date, fewer than 50 cases have been reported worldwide. The present case, hence, is unusual, because the lesion developed on the index finger. Histologically characterized by being poorly delimited tumors with the presence of interstitial scanty cellularity and myxoid material. We discuss the clinical and histological features of digital SA as well as a brief outline of other myxoid lesions. DOI: 10,21276/APALM.1652

Highlights

Superficial acral angiomyxoma (SA) is a rare, slow growing, solitary, soft tissue tumor, which was initially described in 2001. They are usually located on the trunk, but can appear on the lower limbs, head, and neck
SA is a relatively new entity, most likely representing a fibrohistiocytic neoplasm.[1]. They have only been infrequently described on the digit mimicking a digital myxoid cyst
Histopathological examination revealed a dermal tumour composed of bland spindle and stellate cells arranged in a fascicular and storiform pattern against a myxoid and collagenous .The diagnosis of the superficial acral fibromyxoma was considered

Summary

Introduction

Superficial acral angiomyxoma (SA) is a rare, slow growing, solitary, soft tissue tumor, which was initially described in 2001. They are usually located on the trunk, but can appear on the lower limbs, head, and neck. We present a case of 43 years old male who came with complaints of a red raised lesion on the left index finger since 1 year. The lesion had gradually increased to present size and tender to touch. There was no history of trauma or other skin lesions. We received a specimen of soft tissue tumour as multiple skin covered tissue bits aggregating to measure 2x1x1cm and on cut surface had congested appearance. Histopathological examination revealed a dermal tumour composed of bland spindle and stellate cells arranged in a fascicular and storiform pattern against a myxoid and collagenous .The diagnosis of the superficial acral fibromyxoma was considered
