Department of Dermatology, College of Medicine, Chungbuk National University, Cheongju, Korea.

Necrotizing eosinophilic folliculitis is known as a rare variant of eosinophilic folliculitis (EF). It differs from classic EF because of its necrotizing ulcerative clinical course. We report a case of necrotizing eosinophilic folliculitis accompanied by pathergic phenomenon that may be the result of a delayed type hypersensitivity reaction occurring after Rhus consumption.

We describe a case of follicular mucinosis presenting with patchy alopecia affecting the eyebrows. On dermoscopy, white gelatinous material (presumed to be mucin) was visible along the hair shafts of the eyebrow lesions. We propose to call this novel dermoscopic finding the 'toothpaste sign'.

Basaloid follicular hamartoma associated with follicular mucinosis and inflammation.

An Bras Dermatol 2022 Jan-Feb;97(1):45-48. Epub 2021 Nov 14.

Servicio de Dermatología, Hospital Nacional de Pediatría "Prof. Dr. Juan P. Garrahan", Buenos Aires, Argentina.

Basaloid follicular hamartoma is a benign, superficial malformation of hair follicles that can be mistaken both clinical and histopathologically for basal cell carcinoma. Basaloid follicular hamartoma has been linked to a mutation in the PTCH-1 gene, which is part of the same pathway involved in Gorlin-Goltz syndrome. Here we present a 9-year-old patient with an asymptomatic congenital lesion on the forehead, which increased in size over the years. Read More

Eosinophilic folliculitis, eosinophilic dermatosis of hematologic malignancy and acneiform follicular mucinosis: Two case reports and a review of the literature highlighting the spectrum of histopathology.

J Cutan Pathol 2021 Mar 18;48(3):439-450. Epub 2020 Dec 18.

Department of Pathology and Immunology, Washington University School of Medicine, St. Louis, Missouri, USA.

Within the literature, there is overlap in the histopathological features described in eosinophilic folliculitis associated with chronic lymphocytic leukemia (CLL), eosinophilic dermatosis of hematologic malignancy, and acneiform follicular mucinosis. These disorders are described with varying degrees of superficial and deep lymphocytic and eosinophilic inflammation demonstrating perivascular, perifollicular, and folliculocentric involvement with or without follicular mucin deposition. Given significant histopathological overlap, these diagnoses may represent a continuum on a spectrum of dermatoses. Read More

Follicular mucinosis (FM) is an epithelial reaction pattern characterized by follicular mucin accumulation. It has been described in association with various inflammatory and neoplastic cutaneous disorders. FM is generally divided into a primary benign idiopathic form and a secondary form usually occurring in association with cutaneous lymphomas (especially mycosis fungoides), among other entities.

There is no standard therapy for FM and several treatments have been described in the literature. We present the case of a 59 year-old female affected by a recalcitrant FM with diffuse scalp alopecia, in which complete clinical remission was achieved after a combination of topical tacalcitol and photodynamic therapy.

Scleromyxedematous Changes in a Patient With Long-Standing Mycosis Fungoides Who Progressed to Sézary Syndrome.

Am J Dermatopathol 2019 Nov;41(11):e139-e143

Dermatology Service, Division of Subspecialty Medicine, Memorial Sloan Kettering Cancer Center and Weill Cornell Medicine, New York, NY.

Mycosis fungoides (MF) variants with different clinicopathologic and immunohistochemical features have been well-delineated. We report a case of scleromyxedematous changes arising in a patient with long-standing MF who progressed to Sézary syndrome (SS) shortly afterward. Total-skin electron-beam radiation therapy resulted in an excellent response, controlling both the MF/SS and the scleromyxedematous lesions; however, the patient died few months later. Read More

Department of Dermatology, Division of Dermatopathology, Hospital of the University of Pennsylvania, Philadelphia, Pennsylvania.

Background: Cutaneous focal mucinosis (CFM) or focal dermal mucinosis is a benign reactive process categorized as a primary mucinosis. Skin biopsy is essential for diagnosis, as the clinical appearance is often non-specific. Follicular induction is a phenomenon whereby the epidermis is induced by an underlying process to form primitive or mature hair follicles, and is commonly seen overlying dermatofibromas. Read More
