This lesion started as a rash 3 months prior to presentation and became an ulcerated open wound with some nodularity in and around it. What is your diagnosis?
A 30-year-old Caucasian man presented with a left-lower-extremity posterior thigh area skin lesion. The lesion had started as a rash 3 months prior, and in time turned into an ulcerated open wound with some nodularity in and around it. Initial treatments with topical measures, oral antibiotics, and wound care consolidation did not help. There was no history of fevers, chills, night sweats, or weight loss. Physical examination revealed no organomegaly or lymphadenopathy. A biopsy of the skin lesion revealed extensive involvement of skin and subcutaneous tissue by sheets of large atypical cells (A), including C-shaped and multinucleated cells (B) with strong positivity for CD30, CD2, CD45, granzyme B (C), and EMA (epithelial membrane antigen). Immunoperoxidase stains were negative for CD20, PAX5, ALK, pankeratin, S100, MART-1, CD34, and P63.

Locally Advanced Gastrointestinal Stromal Tumor in a 33-Year-Old Woman Seeking to Conceive
August 11th 2020ABSTRACT Gastrointestinal stromal tumors (GISTs) are rare neoplasms of the gastrointestinal tract. They commonly present with nonspecific symptoms and thus are often discovered incidentally. They are best identified by CT scan and most stain positive for CD117 (C-Kit), CD34, and/or DOG-1. Several risk stratification classification systems have been developed based on tumor size, mitotic rate, location, and perforation. Traditional chemotherapy and radiation therapy have been very ineffective, making surgery the mainstay of treatment. The discovery of mutations associated with these tumors has revolutionized the treatment approach. Imatinib mesylate, a selective tyrosine kinase receptor inhibitor, used as adjuvant or neoadjuvant therapy, has greatly improved the morbidity and mortality associated with GISTs. As the survival of patients has increased with the long-term use of targeted therapies, quality-of-life issues now have become much more relevant and have come to the forefront of care. We present a young woman who was successfully treated for GIST but now faces associated long-term adverse effects of imatinib, including the challenge of preserving fertility and the potential for childbearing.
