Are dissecting cellulitis and hidradenitis suppurativa different diseases?

Clin Dermatol 2021 May-Jun;39(3):496-499. Epub 2021 Feb 16.

Dermatology Unit, Department of Clinical Internal, Anesthesiological and Cardiovascular Sciences, Sapienza University of Rome, Rome, Italy.

Although dissecting cellulitis (DC) and hidradenitis suppurativa (HS) are classified separately, they share many clinical, dermatoscopic, pathogenetic, and histologic aspects, as well as therapeutic options. The association between DC, HS, and acne conglobata represents the follicular occlusion triad or follicular occlusion tetrad, which may include a pilonidal sinus. DC, also known as "folliculitis et perifolliculitis capitis abscendes et suffoidens," is classified as a secondary cicatricial and neutrophilic alopecia. 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.

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

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
