Clinical insights into dermatofibrosarcoma protuberans

Dermatofibrosarcoma protuberans (DFSP) is a rare, locally aggressive cutaneous soft tissue sarcoma, it is the second most common skin sarcoma after Kaposi's sarcoma. The cause of DFSP remains unknown. The case of a 54-year-old female patient with a diagnosis of Dermatofibrosarcoma protuberans is presented, displaying a typical clinical presentation. It is characterized by an initial lesion in the form of a reddish spot on the anterior region of the chest, which showed slow growth until the development of a multinodular and irregular lesion with multiple recurrences. The lesion is resected, confined to the superficial layers of the skin, with 3 cm margins, confirming the histopathological diagnosis of dermatofibrosarcoma protuberans with clear margins. DFSP is an uncommon cutaneous sarcoma that is typically low- to intermediate-grade, and while it has a limited likelihood of metastasis, it exhibits a notable tendency for local recurrence. The risk of recurrence is closely linked to the extent of surgical resection

Vascular hamartoma in the distal region of the anterior face of the left forearm, a rare lesion: a case report

The word hamartoma is derived from the Greek word hamartia meaning "to err" or "to blame", with the addition of "-oma" denoting a tumor-like growth. Hamartomas are non-malignant tissue malformations characterized by defective dissemination of fully differentiated cells and soft tissue native to the affected organ. If the tissues involved are composed of blood vessels, they are called vascular hamartomas. In our manuscript we describe the case of a 16-year-old adolescent with the presence of a tumor in the distal region, anterior face of the left forearm, who underwent an excisional biopsy with histopathological report of vascular hamartoma, currently with adequate postoperative evolution. The most commonly reported site of occurrence of vascular hamartomas is on the face and they are generally asymptomatic and silent at different stages of life. The definitive diagnosis for this type of pathology is by histopathology. Vascular hamartomas are a rarely reported benign pathology, due to their low incidence, this can make timely diagnosis difficult, as well as the ideal treatment for these patients
