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.

Combination of tacalcitol ointment and photodynamic therapy for the treatment of follicular mucinosis of the scalp.

Photodiagnosis Photodyn Ther 2019 Sep 9;27:487-489. Epub 2019 Jul 9.

Department of Clinical and Experimental Medicine, Section of Dermatology, University of Messina, Messina, Italy.

Follicular mucinosis (FM) is a rare inflammatory disorder histologically characterized by mucin deposition in the follicular epithelium. 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

Follicular mucinosis in patients with hematologic malignancies other than mycosis fungoides: A clinicopathologic study.

Follicular induction and CK20+ Merkel cells overlying cutaneous focal mucinosis.

J Cutan Pathol 2019 Mar 14;46(3):195-198. Epub 2019 Jan 14.

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

Acneiform follicular mucinosis: an indolent follicular mucinosis variant unrelated to mycosis fungoides?

Clin Exp Dermatol 2018 Dec 30;43(8):921-924. Epub 2018 May 30.

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

Follicular mucinosis (FM) can present as an acneiform eruption, and is usually a benign variant of primary FM unrelated to cutaneous T-cell lymphoma (CTCL). We report two cases of women in their twenties who presented with an acneiform rash on the face, arms and back. In both cases, pathological evaluation of the facial papules revealed predominantly mucinous degeneration of the follicular epithelium, with insufficient lymphocytic infiltration or atypia to diagnose mycosis fungoides.

How to Discern Folliculotropic Mycosis Fungoides From Follicular Mucinosis Using a Pediatric Case.

J Cutan Med Surg 2018 May/Jun;22(3):336-340. Epub 2018 Jan 10.

3 Department of Dermatology, University of Texas MD Anderson Cancer Center, Houston, TX, USA.

Folliculotropic mycosis fungoides (FMF) is a variant of mycosis fungoides (MF) with folliculotropic, atypical lymphocytes that may or may not have mucin deposition surrounding the hair follicle. Follicular mucinosis (FM) is a primary or secondary finding in FMF, lupus, or collagen vascular diseases that is only a histological process of mucin deposition surrounding the hair follicles. We present a case of a 6-year-old boy who had features of both FMF and primary follicular mucinosis (PFM). Read More
