Dermatofibrosarcoma protuberans (DFSP) is rare, generally slow growing tumor, originating from dermal stem cell or undifferentiated mesenchymal cell. DFSP primarily occurs on the trunk and proximal extremities, with reported only 10-15% occurring in the head and neck region. There can be varied presentations of DFSP in atypical sites mimicking a benign appearance and history due to which diagnostic dilemmas can occur. The underlying malignancy needs to be unveiled by histopathology and immunohistochemistry which reveals bland spindle cells in sub epithelium arranged in whorled storiform pattern which was CD34+, suggestive of dermatofibrosarcoma protuberans. Surgical excision is the treatment of choice, wherever possible. We herein report two intriguing cases of DFSP in uncommon sites.

Background: Dermatofibrosarcoma protuberans (DFSP) is a rare proliferative condition representing skin sarcomas known to locally recur yet very rarely known to metastasize. A typical characteristic is trunk localization, making vulvar occurrences an exception. Complete resection is the primary treatment.

Spindle cell lipoma (SCL) is a benign adipocytic tumor usually found in the subcutis of the posterior neck, upper back, and shoulder, predominantly in middle-aged males. This case report describes an atypical presentation of SCL in a 26-year-old male with a history of malignant melanoma. The patient presented with an erythematous plaque with central hyperpigmentation on the right upper arm, an uncommon location and presentation for SCL.

Dermatofibrosarcoma protuberans (DFSP) is a rare, low-grade cutaneous sarcoma typically found on the proximal extremities and the trunk, characterized by infiltrative growth and low risk of metastasis. High rates of local recurrence or relatively large tumor sizes can significantly complicate therapeutic management, particularly when 1) surgical intervention is not adequately performed and /or 2 access to newer medications is limited or their high cost imposes a financial burden on patients. We present the case of a 63-year-old male with a histologically confirmed dermatofibrosarcoma protuberans, measuring 6 cm in diameter, located on the right dorsal region, accompanied by several confluent multifocal nodules situated infralaterally to the primary formation.

Triple primary malignancies are rare, involving the occurrence of three distinct, unrelated cancers in a single patient, requiring a personalized, multidisciplinary treatment approach. A 69-year-old male was diagnosed with dermatofibrosarcoma protuberans (DFSP), lung adenocarcinoma, and papillary thyroid carcinoma. After amputation for DFSP, following staging and genetic evaluation, a multidisciplinary tumor board designed a tailored treatment plan, adjuvant chemotherapy for lung adenocarcinoma while monitor regularly the thyroid carcinoma via ultrasound.
