Abrikossoff's Tumor: An Unusual Presentation
We report a 53-year-old lady who presented to us with a hyperpigmented depressed plaque over her right upper arm of 3 cm × 2 cm of 2 years duration []. It was firm with mild tenderness and was gradually increasing in size. There was no history of discharge from the lesion neither were there any systemic complaints. There was no regional lymphadenopathy. A clinical differential diagnosis of subcutaneous morphea or subcutaneous granuloma annulare was made.\nHistopathology of the lesion revealed a non-encapsulated tumor mass in the dermis and subcutaneous tissue composed of irregularly arranged sheets of large polyhedral cells with indistinct cytoplasmic membranes []. They were found to have an abundant eosinophilic granular cytoplasm, round to oval nucleus, and a small nucleolus. In some places, the granules had formed larger masses called ‘pustulo-ovoid bodies of milian,’ which were surrounded by a clear halo []. The granules were diastase-resistant and PAS-positive []. The overlying epidermis was normal and did not show hyperplasia. Hence, a histological diagnosis of a benign granular cell tumor was made. Our patient underwent a surgical resection of the tumor.
