Infantile Fibrosarcoma With Concurrent Infantile Hemangioma: A Case Report.

This report focuses on the clinical course and treatment of an infant male who had a progressively enlarging tongue mass initially thought to be an infantile hemangioma but was later found to be an infantile fibrosarcoma. Treatment included surgical excision with anticipated difficult mask ventilation with active rhino/enterovirus infection bronchiolitis and recent croup. Complete surgical excision is the mainstay of treatment, and the patient did have negative margins after complete surgical re-excision. The patient has surveillance MRI scans and remains without fibrosarcoma recurrence. This case report highlights complex pediatric airway management and the need for vigilance in healthcare when common presentations, such as infantile hemangioma, also present with a concurrent rare disease at a different anatomic location, such as infantile fibrosarcoma in this case.

Complex sweat gland hamartoma: A case report.

Syringocystadenoma papilliferum (SCAP), tubular apocrine adenoma (TAA), and eccrine nevus are rare benign sweat gland tumors with varied clinical presentations but generally distinctive histomorphologic profiles. TAA and SCAP have been associated with other cutaneous hamartomas, most commonly with nevus sebaceus. Additionally, TAA and SCAP have uncommonly co-occurred in the same lesion. In contrast to nevus sebaceus, eccrine nevus is considerably less common and is rarely associated with other benign adnexal lesions. Here we present an unusual case of a complex sweat gland hamartoma containing features of syringocystadenoma papilliferum, tubular apocrine adenoma, and eccrine nevus in a 7-year-old female.

Cutaneous melanocytic tumor with CRTC1::TRIM11 fusion and prominent epidermal involvement: A case report.

Cutaneous melanocytic tumor with CRTC1::TRIM11 fusion (CMCT) is a recently described entity with only 13 cases reported in the literature. Histopathologically, the neoplasm consists of atypical epithelioid to spindled cells that form a well-circumscribed nodule usually confined to the dermis and subcutis with cytological features including large vesicular nuclei with prominent nucleoli and abundant eosinophilic cytoplasm. Immunohistochemistry shows variable expressivity of melanocytic markers. Currently, there are limited data regarding long-term outcomes of this newly described entity. Most cases have done well, but there is one case reported with an adverse event. Hence, further studies are needed to accurately classify this tumor. Definitive diagnosis is made by laboratory evidence of CMCT. Herein, we report the first case of CMCT with epidermal involvement in the youngest patient known to be affected to date.

Acquired idiopathic generalized anhidrosis: A case series of two Caucasian patients.

Acquired idiopathic generalized anhidrosis (AIGA) is a rare disorder characterized by insidious or sudden onset of the inability to sweat involving >25% of body surface area in the absence of other neurologic or sweat gland abnormalities and typically affects young, healthy, Asian men. Here, we describe two Caucasian teenagers with the diagnosis. They both had variable responses to prednisone, one in the setting of an elevated ANA, suggesting an autoimmune or inflammatory pathomechanism of the disorder. It is essential the clinician recognizes this rare entity and initiates timely intervention to prevent the serious consequences of hyperpyrexia.

A case of idiopathic acquired leukonychia totalis in a 17-year-old boy.

Whitening of the nail, or leukonychia, can have a wide range of etiologies including genetic disorders, trauma, poisoning, autoimmune disorders, and infections. Here we detail a case of idiopathic acquired leukonychia totalis in a 17-year-old boy. This condition has been reported 13 times in the literature previously, with only young boys being affected. Proper diagnosis may help minimize unnecessary investigations and prevent additional psychological stress over whether an underlying disease is present.

Multiple atypical vascular lesions following breast-conserving surgery and radiation.

Atypical vascular lesions (AVLs) of the breast are purple papules or nodules that have been reported in breast cancer patients following radiation treatment, typically presenting with fewer than 5 lesions at diagnosis. We report a patient with 29 lesions within previously irradiated breast tissue. Due to the large number of lesions and concern for development of angiosarcoma, the patient's case was brought before a multidisciplinary tumor board that decided she should undergo a radical mastectomy with flap reconstruction. We discuss the dermatologist's role in managing this complex and increasingly common disorder.
