Chromoblastomycosis (CMB) is a cutaneous fungal infection caused by dematiaceous fungi. According to the World Health Organization CMB has been elected as a tropical disease, and it is prevalent in tropical and subtropical regions. The lower extremities are the most affected areas, and the lesions progress with erythema, papules, nodules, verrucose plates and/or ulcerations. So far, few works have demonstrated neoplastic transformation in chronic CMB lesions, and it may be a consequence of prolonged inflammatory response. In the present case report, we described a neoplastic transformation from CMB lesion of a 55- year-old man, presenting lesions only in the left leg for 35 years. After treatment, a verrucous white plate with thick and irregular borders emerged in the ankle, which was identified as a sarcomatoid squamous cell carcinoma. The present case report highlights the importance of an early diagnosis and treatment.

Birt-Hogg-Dubé syndrome (BHDS) is an autosomal dominant inherited disorder caused by mutation in a tumour suppressor gene, FLCN, leading to skin tumours (fibrofolliculomas), renal tumours and pulmonary cysts. Lung involvement is predominantly observed in 70% of the cases of BHDS, manifesting in the form of recurrent primary spontaneous pneumothorax. This video tutorial showcases the surgical management of recurrent right primary spontaneous pneumothorax in a young adult with a history of multiple episodes of bilateral pneumothorax managed by surgical intervention previously.

The patient had rheumatic heart disease, which resulted in severe aortic and mitral valve regurgitation. Repair of both valves was performed at 9 years of age. During surgery, the retracted aortic valve cusps required extension with bovine pericardial patches and suture reduction annuloplasty, and the mitral valve was repaired using a Cosgrove-Edwards (Edwards Lifesciences LLC, Irvine, CA) annuloplasty band.

Myoepithelial carcinoma (MECA) is a malignant neoplasm composed exclusively of myoepithelial cells and accounts for less than 1% of all salivary gland tumors. Its diagnosis is often challenging due to histologic overlaps with benign lesions and its variable morphologic presentation. Although molecular profiling has emerged as a valuable tool in salivary gland tumor classification, the genetic landscape of MECA remains incompletely defined.

Purpose: To share our clinical experience with conservative management of isolated spinal arterial aneurysms (ISAs) and to identify clinical scenarios where conservative management may be appropriate, in the context of a literature review.
Methods: We performed a retrospective review of spinal angiograms from two German neuroradiology centers and conducted a systematic literature review of reported ISA cases. We analyzed demographics, clinical presentation, imaging findings, treatments, and outcomes.
