Arch Dermatol Res 2021 Jun 15. Epub 2021 Jun 15.

Dr. Phillip Frost Department of Dermatology and Miami Itch Center, University of Miami, Miami, FL, USA.

Chronic pruritus carries a significant burden of disease and is associated with a negative impact on quality of life. African Americans are disproportionately burdened by chronic pruritic disorders, including but not limited to atopic dermatitis, prurigo nodularis, inflammatory scalp dermatoses, pathologic scarring, and HIV-related dermatoses.

Although not completely understood, its etiopathogenesis seems to be multifactorial, including association with metabolic syndrome (MetS). Despite being commonly seen in patients with MetS, obesity per se as a possible related factor for AKN has yet to be studied. Read More

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

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.
