Alopecia neoplastica (AN) is caused by neoplastic cells damaging hair follicles, resulting in patchy hair loss like cicatricial alopecia and alopecia areata. AN has predominantly described cutaneous metastasis to the scalp from primary visceral malignant tumors. Less frequently, AN results from a primary scalp neoplasm. Compared to "secondary AN," there is a paucity of literature on "primary AN." Herein, we present a comprehensive literature review of primary AN and introduce a unique case of amelanotic melanoma causing primary AN. Including our presented case, 11 cases of primary AN have been reported with causative scalp neoplasms including angiosarcoma, hemangioendothelioma, syringomatous carcinoma, ectopic extramammary Paget's disease, and primary desmoplastic melanoma. 27.3% (3 of 11) of cases were misdiagnosed and treated for a primary alopecia, and 36.4% (4 of 11) of lesions were present for multiple years or an unknown amount of time, likely due to difficulty in recognizing scalp lesion or misdiagnosis. All patients required surgical excision with 36.4% (4 of 11) requiring chemotherapy, radiation, or photodynamic therapy. Two patients with scalp angiosarcoma died from their aggressive disease. Due to the risks of malignant primary AN if allowed to progress, primary AN should be considered in patients presenting with scarring alopecia.
RESUMEN
INTRODUCTION: Tocilizumab (TCZ), a recombinant humanized antihuman monoclonal antibody targeting interleukin-6 (IL-6) signaling, is often utilized in the management of autoimmune disease. Few reports have demonstrated hair growth changes in patients on TCZ. CASE PRESENTATION: Herein, we review the literature and report a 21-year-old woman with progressive alopecia areata (AA) presenting with AA improvement while on TCZ for concomitant posterior uveitis. DISCUSSION: Our case demonstrates the potential ability of TCZ to disrupt IL-6 signaling involved in AA, leading to hair loss and regrowth.
RESUMEN
Pulmonary carcinoid tumors are uncommon neuroendocrine tumors that rarely metastasize to the skin. We report the case of a 71-year-old woman with a longstanding history of primary atypical pulmonary carcinoid tumor who presented with a new tender cutaneous nodule. Immunostaining of the nodule was consistent with metastatic atypical carcinoid tumor of the skin including positive staining for neuroendocrine markers chromogranin and synaptophysin. Dermatologists should consider cutaneous neuroendocrine metastasis when evaluating new nodules in patients with stable pulmonary carcinoid tumors or in those with concomitant concerning respiratory symptoms.

Treatment options for hair loss have traditionally been limited to topical and systemic therapies. Systemic therapies for inflammatory hair disorders are often immunosuppressive, and systemic treatment of androgenetic hair loss can cause undesired effects on sexual and reproductive health. Topical agents have a favorable side effect profile compared with systemic therapies, but many topicals have poor transcutaneous absorption, limiting their concentration and action at follicular targets in the dermis.

BACKGROUND AND OBJECTIVES: Gender-affirming hormone therapy (GAHT) is a key component in the primary care of transgender and gender-nonconforming (TGNC) people. However, physicians are hesitant to initiate GAHT, citing a lack of knowledge. We developed an educational program for medical students and sought to investigate whether medical students' comfort and familiarity with GAHT could increase after a short interactive program. METHODS: Second-year medical students (N=54) at the University of Minnesota were recruited to attend an hour long interactive lecture on GAHT. We calculated mean change in pre- and postintervention 5-point Likert scale scores from a survey assessing comfort and familiarity with key concepts of GAHT to assess the effectiveness of the intervention. RESULTS: Mean response score change increased significantly after the intervention around the use of chosen names (0.4±0.13, P<.017), the use of informed consent to initiate GAHT (1.8±0.20, P<.001), initiating and managing GAHT in the primary care setting (1.4±0.19, P<.001), medications used in GAHT (2.3±0.21, P<.001), and dosing (2.5±0.60, P<.001). CONCLUSIONS: GAHT can be initiated and managed in a primary care setting. There is a push to introduce GAHT in the preclinical years. After participating in a short interactive lecture on GAHT, second-year medical students reported increased comfort and familiarity with GAHT. Inclusion of GAHT in the preclinical curriculum does not require significant teaching time and is important knowledge for all future physicians.
