Dermatofibrosarcoma Protuberans Arising From a Chronic Wound in the Left Shoulder: A Case Report

Dermatofibrosarcoma protuberans (DFSP) is a rare, slow-growing soft tissue sarcoma, typically presenting as a cutaneous lesion. However, its occurrence in chronic wounds is infrequently documented, posing diagnostic and therapeutic challenges. This report details the case of a 59-year-old female with no significant medical history, presenting with a chronic, non-healing wound on the left shoulder, persisting for three years. Initially a small nodule, it progressed into an ulcerating lesion. Physical examination revealed a contracted scar with restricted shoulder mobility. After obtaining informed consent, a surgical excision of the lesion was performed by an electrocautery. Histopathology confirmed DFSP, characterized by spindle fibrous cells, with skin ulceration and deep dermal infiltration. A split-thickness skin graft achieved successful closure. This case underscores the importance of considering DFSP in chronic, non-healing wounds. Timely intervention and appropriate surgical management are crucial for favorable outcomes.

A Rare Presentation of Donkey Bites Involving the Cheek and Ear: A Case Report and Literature Review

Although animal bites account for a fair number of emergency department visits, donkey bites account for a very limited proportion. A 12-year-old boy presented to our department with a severe donkey bite involving his face. The injury included his left cheek with a laceration of the left ear cartilage. The examination revealed no serious morbidity (no vascular or nerve involvement). The patient received prophylactic antibiotics and anti-rabies/anti-tetanus vaccination. The wound was cleaned thoroughly with copious irrigation. Afterward, the patient underwent surgery to correct the defect in the cheek using a rotational advancement cervicofacial flap, while the penetrated ear cartilage was repaired and the skin margins were approximated and sutured. During the follow-up period, no complications were observed and the functional and cosmetic outcomes were satisfactory. Donkey bites are rarely encountered and they can result in different presentations and morbidities/outcomes. It is suggested that the timing from the bite injury to presentation, the stage/extent of the bite, the use of anti-tetanus and anti-rabies vaccines, and the prophylactic use of antibiotics may play a role in determining the outcomes and/or complications of donkey bites.
