Primary tumors of serosal surfaces are uncommon in veterinary medicine. Mesothelial neoplasms can be benign or malignant, and are classified as predominantly epitheloid, mixed (biphasic), or fibrous (spindle cell, fibrosarcomatous), with fibrous mesotheliomas reported least in domestic species. A 9-year-old Domestic Shorthair cat presented on emergency with a brief history of weakness and letha...

Background Dermatofibrosarcoma protuberans (dfsp) is a rare tumour originating from the dermis, it is slow growing, nodular, polypoid neoplasm that invade the subcutaneous tissue and does not usually metastasis.Clinical presentation is not uniform and may mimic common tropical benign skin lesions.We intend to study the behaviour of this tumour in our environment . Materails and method. A Clinic...

Dermatofibrosarcoma protuberans (DFSP) is a rare cutaneous tumor with a possibly misleading presentation. It is rare in childhood. We report an 18-month-old child with an acquired atrophic plaque of the left ankle. Based on clinical findings, initial proposed diagnoses included localized scleroderma and localized lipoatrophy. At the age of 5 years the plaque had increased in size and become a p...

Dermatofibrosarcoma protuberans is a rare cutaneous tumor with particular characteristics and a high frequency of recurrence after inadequate primary treatment. Its histopathological diagnosis might be difficult. Dermatofibrosarcoma protuberans can be safely distinguished from other similar neoplasms of mesenchymal origin based on the immunohistochemical expression of CD34 antigen and the genet...

INTRODUCTION Dermatofibrosarcoma protuberans is an uncommon low-grade soft tissue sarcoma with a high potential for recurrence as it has irregular finger like extensions. CASE DESCRIPTION We report a case of a large, recurrent dermatofibrosarcoma protuberans in a child involving the anterior abdominal wall, which posed a challenge for reconstruction. Peritoneum sparing full thickness resectio...

BACKGROUND Processing multiple tissue sections in large Mohs cases is time consuming and labor intensive. OBJECTIVE To present innovative laboratory techniques to facilitate processing of large Mohs cases. METHODS A method for processing a large dermatofibrosarcoma protuberans Mohs case is outlined. RESULTS Modifications in tissue processing and equipment employed in a large Mohs case are...
