Diagnosis and Management of Dermatofibrosarcoma Protuberans in a 3-Year-Old Patient
In this case report, we present a 3-year-old boy with a diagnosis of dermatofibrosarcoma protuberans (DFSP) on the dorsum of his right hand. Although rarely metastatic, DFSP is highly locally invasive and can cause considerable local morbidity. In the hand, DFSP is uncommon in the young pediatric patient. In our patient, the tumor extended down to the second and third metacarpal heads and was treated with a multistaged excision of his tumor to achieve negative margins under slow Mohs micrographic surgery.Eccrine Porocarcinoma Presenting as a Hand Cyst
Eccrine porocarcinoma is a rare tumor that arises from the epithelium of the eccrine ducts, with a tendency for metastatic spread and a high rate of local recurrence after excision. It was first described in 1963 by Pinkus and Mehregan and can present clinically as a nodule, erosive plaque or a polypoid growth that may ulcerate. The variable clinical appearance of these lesions can make diagnosis challenging and could delay appropriate treatment. If metastasis occurs the prognosis is poor, with a reported mortality rate of up to 80%.
