Abstract:
This case presents incidental heterotopic salivary gland tissue adjacent to a dermatofibrosarcoma protuberans (DFSP) located in the abdominal wall. The mature, functional heterotopic tissue was identified during Mohs micrographic surgery (MMS) performed for a DFSP, a slow-growing cutaneous tumor with locally aggressive and potentially malignant behavior. Definitive diagnosis of the heterotopic tissue was confirmed by histopathological examination and immunohistochemical analysis. This case underscores the importance of being alert to unusual tissue findings at the time of MMS and the value of close collaboration between dermatologists and pathologists.
