Background: Dermatofibrosarcoma protuberans a rare soft tissue tumour that involves the dermis, subcutaneous fat, and in cases muscle fascia. Case Report: 34 yr old female patient presented with history of swelling front right ear since 2 years, associated pain weeks , HRUSG neck reported as Neoplastic pathology FNAC benign spindle cell tumor. Patient underwent surgical excision tumour. Frozen ...

Dermatofibrosarcoma protuberans (DFSP), the most common dermal sarcoma, is a low-grade, slow growing fibroblastic malignant neoplasm that most frequently affects middle aged adults and is characterized by a high local recurrence rate and a low propensity for metastasis. Wide surgical resection or Mohs micrographic surgery (MMS) are the preferred approaches for localized disease, while radiation...

Dermatofibrosarcoma protuberans (DFSP) is an uncommon locally aggressive mesenchymal tumor with a high local recurrence rate. Atrophic DFSP is a rare variant of DFSP characterized by a non-protuberant lesion. We report on a 23-year-old female, who presented with an atrophic, asymptomatic macule on the right side of her back 2 cm in diameter. Dermatoscopic examination revealed homogenous pigment...

BACKGROUND Dermatofibrosarcoma protuberans (DFSP) is an uncommon low-grade fibrohistiocytic tumor that usually occurs on the trunk or proximal extremities and typically appears during the second to fifth decade of life. It most commonly begins as a red-blue plaque that grows slowly and ultimately becomes nodular. The tumor is associated with a high recurrence rate but low metastatic potential. ...

The genetic changes leading to the development of malignant peripheral nerve sheath tumors (MPNSTs) are largely unknown. The few tumors that have been investigated cytogenetically had highly complex karyotypes and no consistent rearrangements, and the attempts to pinpoint consistent DNA-level changes have met with only limited success. We used comparative genomic hybridization to analyze seven ...
