A case of hidradenitis suppurativa with perifolliculitis capitis abscedens et suffodiens successfully treated with a human anti- tumor necrosis factor monoclonal antibody.

Clin Exp Dermatol 2021 Jun 7. Epub 2021 Jun 7.

Department of Dermatology, Hirosaki University Graduate School of Medicine, Aomori, Japan.

Hidradenitis suppurativa (HS) is a chronic autoinflammatory skin disorder characterized by recurrent painful nodules, abscesses, sinus tracts, and scarring on intertriginous body areas. Perifolliculitis capitis abscedens et suffodiens (PCAS) is a component of the follicular occlusion tetrad along with HS, acne conglobata, and pilonidal cyst. We report a case of HS with PCAS that was successfully treated with adalimumab, a human anti-tumor necrosis factor (TNF) monoclonal antibody. Read More

Ancient friends, revisited: Systematic review and case report of pyoderma gangrenosum-associated autoinflammatory syndromes.

J Transl Autoimmun 2020 20;3:100071. Epub 2020 Nov 20.

Department of Dermatology, The Saarland University Hospital, 66421, Homburg, Germany.

In the last decade, new scientific findings significantly improved our understanding of the molecular pathogenesis of autoinflammation and have resulted in the identification and definition of several pyoderma gangrenosum-associated autoinflammatory syndromes (PGAAIS) as new and distinct clinical entities. These different clinical entities include PAPA (pyogenic arthritis, pyoderma gangrenosum and acne conglobata), PASH (pyoderma gangrenosum, acne and suppurative hidradenitis), PAPASH (pyoderma gangrenosum, acne, suppurative hidradenitis and pyogenic arthritis), PsAPASH (pyoderma gangrenosum, acne, suppurative hidradenitis and psoriatic arthritis), PASS (pyoderma gangrenosum, acne conglobata, suppurative hidradenitis, and axial spondyloarthritis) and PAC (pyoderma gangrenosum, acne and ulcerative colitis), which can be distinguished by their clinical presentation and the presence or absence of mutations in several genes, such as the genes encoding proline-serine-threonine phosphatase-interacting protein 1 (PSTPIP1), nicastrin (NCSTN), Mediterranean fever (MEFV) and nucleotide-binding oligomerization domain-containing protein (NOD). In this systematic review, we summarize the present knowledge of this rapidly developing hot topic and provide a guide to enable the easy diagnosis of these syndromes in everyday clinical practice.

Department of Pediatric and Adolescent Medicine, Western Michigan University, Homer Stryker M.D. School of Medicine, 1000 Oakland Drive, Kalamazoo, MI 49008-1284, United States.

Acne vulgaris is a chronic, inflammatory, skin condition that involves the pilosebaceous follicles and is influenced by a variety of factors including genetics, androgen-stimulation of sebaceous glands with abnormal keratinization, colonization with Cutibacterium acnes (previously called Propionibacterium acnes), and pathological immune response to inflammation. Acne can occur at all ages and this discussion focuses on the first three decades of life. Conditions that are part of the differential diagnosis and/or are co-morbid with acne vulgaris are also considered. Read More

Follicular occlusion triad: an isotopic response or adverse effect of rituximab?

Dermatol Online J 2020 Feb 15;26(2). Epub 2020 Feb 15.

Department of Dermatology, University of Illinois at Chicago, Chicago, IL.

Follicular occlusion triad is a symptom complex of three conditions with a similar pathophysiology including hidradenitis suppurativa (HS), dissecting cellulitis of the scalp, and acne conglobata. Although the exact pathogenesis of the triad is unknown, it appears to be related to follicular occlusion in areas with apocrine glands. Wolf isotopic response refers to the occurrence of a new dermatosis at the site of another, unrelated, previously healed dermatosis. Read More

Follicular occlusion tetrad in a male patient with pachyonychia congenita: clinical and genetic analysis.

J Eur Acad Dermatol Venereol 2019 Oct;33 Suppl 6:36-39

Dermatology Clinic, University of Catania, Catania, Italy.

The case of a 24-year-old male patient affected by follicular occlusion tetrad (acne conglobata, hidradenitis suppurativa, pilonidal cyst and dissecting cellulitis of the scalp) associated with clinical signs of pachyonychia congenita (PC)-2 (focal palmoplantar keratoderma, plantar pain, onycodystrophy and multiple cysts) is reported. The diagnosis was supported by genetic analysis that showed heterozygous mutation within the exon 1 of KRT17 gene. This case may reflect different expressions of a phenotypic spectrum induced by a common genetic alteration. Read More

Perifolliculitis capitis abscedens et suffodiens treatment with tumor necrosis factor inhibitors: A case report and review of published cases.

J Dermatol 2019 Sep 4;46(9):802-807. Epub 2019 Jul 4.

Department of Dermatology, Tohoku University Graduate School of Medicine, Sendai, Japan.

Perifolliculitis capitis abscedens et suffodiens (PCAS) or dissecting cellulitis is a rare condition presenting deep follicular occlusions, follicular ruptures and follicular infections in the scalp area with unknown etiology, which consequently cause primary neutrophilic cicatricial alopecia by the repeated follicular inflammation. PCAS is categorized as one of the "follicular occlusion tetrad" along with hidradenitis suppurativa, acne conglobata and pilonidal cyst. In the pathogenesis of the follicular occlusion tetrad, the involvement of neutrophils and its activator tumor necrosis factor (TNF) have been discussed. Read More

Consultant Geriatrician, Proactive Care of Older People undergoing Surgery (POPS), Department of Ageing & Health, Guy's and St Thomas' NHS Foundation Trust, London.

As a consequence of an ageing population greater numbers of elderly patients are presenting for both elective and emergency surgery. These older patients typically present with an increased burden of age-related problems and multimorbidity, which is associated with an increased risk of adverse postoperative outcomes. Traditional preoperative assessment models are adept at discerning patients' suitability for anaesthesia and surgery, but there is minimal focus on improving postoperative outcomes. Read More

Could isotretinoin flare hidradenitis suppurativa? A case series.

Clin Exp Dermatol 2019 Oct 22;44(7):777-780. Epub 2019 Mar 22.

Department of Dermatology, Tallaght University Hospital, Tallaght, Dublin 24, Ireland.

We report eight cases of patients with severe acne who were treated with isotretinoin and developed painful nodules in the axillae and groin, consistent with hidradenitis suppurativa (HS). The pathogenesis of HS is still not completely understood; recent research from a study in 2011 of biopsies from HS lesions showed a reduction or absence of sebaceous glands compared with normal skin in patients with HS, with the report suggesting that this contributes to the pathogenesis of the disease. Interestingly, the main effect of isotretinoin is to decrease the size and action of sebaceous glands, so hypothetically, as isotretinoin acts by reducing the sebaceous glands further it could potentially aggravate HS.
