Surgical management of concurrent histiocytoma and dermatophytosis in an 8-month-old male Boarboel dog

An 8-month-old male Boarboel dog was presented with a mass on the rostral aspect of the face which bled consistently. The patient also had areas of alopecia on the left hind limb, right forelimb, head, and abdominal regions. The mass progressively increased in size with time without regression. Radiographic examination of the chest showed no evidence of metastasis. Cultures of the skin swab as well as that of the bleeding facial swelling yielded heavy growth of Staphylococcus sp. (+++) while the skin scraping yielded heavy growth of Microsporum canis. Microscopically, the growth was a hypercellular mass, composed of tightly packed, slightly pleomorphic cells in the dermis which partially obliterated the adnexal structures and dermal collagens. Surgical excision of the mass with combined topical and systemic antifungal treatment yielded a perfect therapeutic result for both conditions.
