Dilation of Multiple Eccrine Ducts as a Highly Specific Marker for Cicatricial Alopecia.

Am J Dermatopathol 2019 Dec;41(12):871-878

Assistant Professor, Department of Dermatology, Northwestern University Feinberg School of Medicine, Chicago, IL.

Background: Eccrine duct dilation (EDD) was recently described to occur more frequently in cicatricial alopecias than noncicatricial alopecias. Because single EDD can be useful in the evaluation of alopecias, we aimed to determine whether dilation of multiple eccrine duct units, or "multiple eccrine duct dilation (MEDD)," could more specifically discriminate between cicatricial and noncicatricial alopecias.

Methods: We retrospectively evaluated 611 scalp biopsies (342 cicatricial alopecias and 269 noncicatricial alopecias). Read More

Hidradenitis Suppurativa in a Patient with Smith-Magenis Syndrome: A Case Report.

Cureus 2019 Jun 22;11(6):e4970. Epub 2019 Jun 22.

Dermatology, David Geffen School of Medicine at University of California Los Angeles, Los Angeles, USA.

Hidradenitis suppurativa (HS) is an inflammatory disorder characterized by recurrent painful nodules and draining sinus tracts with subsequent scarring. HS has been associated with several dermatologic syndromes including the follicular occlusion tetrad, PASH (pyoderma gangrenosum, acne, and suppurativa hidradenitis), PAPASH (pyogenic arthritis, pyoderma gangrenosum, acne, and suppurativa hidradenitis), and SAPHO (synovitis, acne, pustulosis, hyperostosis, and osteitis) syndromes. However, aside from the well-established association between HS and Down Syndrome, it has rarely been reported in association with other multisystem genetic diseases. Read More

Premature Desquamation of the Inner Root Sheath in Noninflamed Hair Follicles as a Specific Marker for Central Centrifugal Cicatricial Alopecia.

Am J Dermatopathol 2019 May;41(5):350-354

Dermatology, Feinberg School of Medicine, Northwestern University, Chicago, IL.

Background: Premature desquamation of the inner root sheath (PDIRS) is considered one of the distinctive features in central centrifugal cicatricial alopecia (CCCA). However, PDIRS can be seen in other alopecia subtypes, and its utility in the diagnosis of CCCA has been debated. We aimed to examine a large cohort of alopecia cases for the presence of PDIRS in association with and without inflammation to determine whether PDIRS in noninflamed follicles can be used as a specific marker of CCCA.

Naked Hair Shafts as a Marker of Cicatricial Alopecia.

Am J Dermatopathol 2018 Jul;40(7):498-501

Departments of Dermatology, and.

Naked hair shafts (NHS) are free-floating hair shafts devoid of surrounding epithelium, supporting structures, and/or embedded in inflammation that may result from destruction of hair follicles by scarring processes such as inflammation and fibroplasia. Extensive examination of NHS has not been performed in scalp biopsies of alopecia. We retrospectively evaluated 622 scalp biopsies of alopecia [345 cicatricial alopecias (central centrifugal cicatricial alopecia, lichen planopilaris, discoid lupus erythematosus, acne keloidalis nuchae, and folliculitis decalvans] and 277 non-cicatricial alopecias [alopecia areata, androgenic alopecia, telogen effluvium, and psoriatic alopecia)] for the presence of NHS.

Acne keloidalis nuchae (AKN) also known as folliculitis keloidalis nuchae (FKN) is a chronic form of scarring folliculitis seen mostly in men of African descent. The term AKN is commonly used even though the condition is not a keloid, and the affected individuals do not have a tendency to develop keloids in other areas of the body. It is seen in post pubertal men and is rare after the age of 55 years. Read More

Department of Dermatology and Cutaneous Surgery, University of Miami Miller School of Medicine, Miami, FL, USA.

Acne keloidalis nuchae (AKN) is a chronic inflammatory condition that leads to fibrotic plaques, papules and alopecia on the occiput and/or nape of the neck. Traditional medical management focuses on prevention, utilization of oral and topical antibiotics, and intralesional steroids in order to decrease inflammation and secondary infections. Unfortunately, therapy may require months of treatment to achieve incomplete results and recurrences are common. Read More

Servicio de Dermatología, Fundación Jiménez Díaz, Universidad Autónoma, Madrid, España. Electronic address:

The diagnosis of disorders of the hair and scalp can generally be made on clinical grounds, but clinical signs are not always diagnostic and in some cases more invasive techniques, such as a biopsy, may be necessary. This 2-part article is a detailed review of the histologic features of the main types of alopecia based on the traditional classification of these disorders into 2 major groups: scarring and nonscarring alopecias. Scarring alopecias are disorders in which the hair follicle is replaced by fibrous scar tissue, a process that leads to permanent hair loss. Read More

Health risks of the clean-shave chiskop haircut.

S Afr Med J 2013 May 27;103(7):489-90. Epub 2013 May 27.

Division of Dermatology, Faculty of Health Sciences, University of Cape Town, South Africa.

During a previous study, participants described an unexpected symptom of haircut-associated bleeding. As this is not a widely recognised entity, we conducted the present study at an HIV clinic servicing the same population, with the objective of comparing the prevalences of haircut-associated bleeding and FKN in 390 HIV-positive subjects with published data for Langa (Western Cape, South Africa).
