Dermatofibrosarcoma Protuberans in Abdominal Wall Aggravated during Pregnancy

ABSTRACT

Dermatofibrosarcoma protuberans is a rare tumor that occurs in the dermis or subcutaneous tissue of the trunk or extremities in relatively young adults. There are few reports of Dermatofibrosarcoma protuberans associated with pregnancy. We experienced a 28-year-old pregnant female patient with an abdominal wall mass, which grew rapidly during pregnancy. Excisional biopsy was performed and the pathologic diagnosis was fibrosarcoma transformed from Dermatofibrosarcoma protuberans. Dermatofibrosarcoma protuberans showed a positive CD34 immunostaining while fibrosarcoma showed a negative CD34. There was no recurrence or metastasis with the follow up period of 2 years. We report here a rare case of Dermatofibrosarcoma protuberans aggravated during pregnancy with a review of the literature.
