title: Aggressive Digital Papillary Adenocarcinoma-A rare Entity Posing a Diagnostic Challenge.
abstract: Aggressive digital papillary adenocarcinoma (ADPCA) is rare tumor of the sweat glands, which is characterised by lesions on the fingers, toes and the digits. The lesion is serious but often overlooked because it is confused clinically with benign and non-tumorous entities. In this paper, we present an interesting case of ADPCA in a 40-year-old lady, suspected clinically as pyogenic granuloma, with the initial excision biopsy indicating a malignant tumor in the sweat gland. Ray amputation of the affected finger was done followed by a thorough work up to rule out metastasis. Histopathological features were studied in detail, along with required markers. We present this case as the documentation of this malignant tumor is limited in literature and also it requires a high index of suspicion when dealing with all masses arising on the digits.
