Giant benign lymphangioendothelioma with positive expression of Wilms tumor 1: A case report.

Benign lymphangioendothelioma (BL, acquired progressive lymphangioma) is a rare, slow-growing lymphatic tumor, first described 40 years ago, with fewer than 50 published cases. Clinically, it presents as a skin-colored or erythematous patch. Definitive diagnosis requires histopathological examination.

Cutaneous Angiosarcoma in an Unusual Location and Without Predisposing Factors.

Unlabelled: Cutaneous angiosarcoma is a rare, highly malignant tumour of vascular endothelial origin. It usually arises in the skin and superficial soft tissue, mostly on the head and neck. It presents as a variety of lesions, and so is considered a great mimicker, leading to a delay in diagnosis and evidencing the importance of biopsy with immunohistochemistry confirmation.

An Exuberant Case of Necrobiotic Xanthogranuloma.

Necrobiotic xanthogranuloma (NXG) is a rare form of inflammatory granulomatous disease of the skin characterized by the presence of pruritic to painful lesions, generally located in the periorbital area, although trunk and proximal extremities may also be involved. We report a case of a 69-year-old male patient with extensive involvement of the trunk, upper and lower extremities, and an associated gamma monoclonal gammopathy. The skin biopsy was consistent with the diagnosis of NXG.

Mycobacterium abscessus infection in a spa worker.

Mycobacterium abscessus (M. abscessus) is a non-tuberculous mycobacterium widely present in the natural environment and is now being increasingly identified as a cause of human disease. However, it can cause skin and soft tissue infection following trauma or surgery.

Surgical Pearl on Reconstructing Surgical Defects of the Nasal Tip.

Repairing surgical defects of the nasal tip is challenging, mainly because of the lack of freely mobile skin available peripherally. The Peng flap is a one-stage cutaneous flap that circumvents this difficulty by recruiting skin from the nasal and sidewall regions. The design produces a tridimensional shape perfectly adapted to the configuration of the nasal tip and allows for an inconspicuous closure of the defect.

Cutaneous Richter Syndrome mimicking a lower limb cellulitis infection - a case report and review of the literature.

Richter syndrome (RS) is characterized by the development of a high-grade lymphoma in patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). Herein, we present the case of an 85-year-old woman with a 3-year history of stable asymptomatic CLL that developed a cutaneous RS. The patient presented with painless inflammation in the left leg and foot that was initially diagnosed as a cellulitis infection.

Erythroderma. A clinical and etiological study of 103 patients.

Background: Erythroderma is an uncommon and severe dermatological manifestation of a variety of diseases. It is commonly challenging to find the underlying cause.

Objective: The aim of this study was to analyze the causes of the disease in patients with erythroderma.

Pigmented lesion of the nipple - a clinicopathological challenge.

Differential diagnoses of pigmented lesions of the nipple include melanocytic nevus, melanosis of the nipple, seborrheic keratosis, pigmented basal cell carcinoma, melanoma and Paget disease. The histologic exam with appropriate immunohistochemistry is a fundamental tool to achieve a correct diagnosis. We present a patient with a pigmented lesion of her right nipple revealing mammary Paget disease and elucidate diagnostic obstacles and prognostic importance of early breast cancer detection.
