Primary Alopecia Neoplastica: A Novel Case Report and Literature Review.

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.

Hair Growth in a Patient with Alopecia Areata on Tocilizumab.

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.

Subcutaneous metastasis from an atypical pulmonary carcinoid tumor.

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.

Nail disease in neonatal abstinence syndrome.

BACKGROUND/OBJECTIVES: Neonatal abstinence syndrome (NAS) incidence continues to rise in the United States due to increasing opioid use disorder in pregnancy. While cutaneous excoriations have been noted in NAS, there is a paucity of literature regarding abnormal nail findings in NAS. METHODS: A retrospective, observational case series was conducted of twelve patients with NAS and abnormal nail findings who were admitted to the neonatal intensive care unit between January 1, 2018, and May 1, 2020. RESULTS: Twelve neonates (10 male, 2 female, mean gestational age at birth 38.1 weeks) with NAS diagnosis and abnormal nail findings were identified between January 1, 2018, and May 1, 2020. NAS was diagnosed by elevated Modified Finnegan Neonatal Abstinence Syndrome Tool (M-FNAST) scores. All patients required pharmacologic treatment for NAS with seven (58.3%) requiring phenobarbital in addition to first-line morphine. Common nail findings included periungual erythema, yellow crusting, desquamation of the proximal and/or distal lateral nail folds and sheared distal nail edges. Two patients (16.7%) required antibiotic treatment for paronychia. Peak M-FNAST scores were positively correlated with number of abnormal nail findings (r = .58, P = .047). CONCLUSIONS: Twelve neonates with severe NAS demonstrated similar nail abnormalities, likely secondary to NAS agitation and motor hyperactivity. Nail exams, therefore, are important in the setting of suspected or confirmed NAS to limit continued nail trauma and infection. Our findings also introduce an association between NAS severity and abnormal nail findings, which will require larger studies for further confirmation.

Sweet syndrome with perifollicular involvement because of koebnerization from facial hair plucking.

Sweet syndrome (SS), also known as acute febrile neutrophilic dermatosis, is an uncommon skin eruption characterized by fever, leukocytosis, and tender erythematous papules, nodules, and plaques. Histopathologically, SS lesions are characterized by marked superficial papillary edema with a dense neutrophilic infiltrate. SS is known to demonstrate both the Koebner phenomenon and pathergy. The majority of reported cases of these phenomena occur following significant cutaneous injury (e.g., biopsies, burns) rather than minor trauma such as pressure and friction. Here, we present the first known reported case of SS koebnerization secondary to minor grooming-related hair plucking. In addition, this is also the first reported case to our knowledge of SS with perifollicular involvement on histopathology.

Botanical Briefs: Phytophotodermatitis Caused by Giant Hogweed (Heracleum mantegazzianum).

Giant hogweed (Heracleum mantegazzianum) is an invasive flowering weed that can reach a height of 13 feet. Although it is the appearance of the plant that can draw attention, contact with the sap in combination with exposure to the sun can result in severe phytophotodermatitis. Due to the growing prevalence of giant hogweed, the number of cases of H mantegazzianum-associated phytophotodermatitis in the United States is increasing. We report the case of a 27-year-old man who presented with a blistering rash on the neck and arms that developed 18 to 24 hours after trimming giant hogweed plants without photoprotection. A diagnosis of giant hogweed phytophotodermatitis should be considered for patients presenting with acute erythema and bullae in sun-exposed areas after exposure to the plant. Additionally, the public would benefit from education, especially during summer months, on identifying the plant and reducing phototoxin exposure to reduce the risk for phytophotodermatitis.
