Perifolliculitis histology

The importance of histopathologic aspects in the diagnosis

Dissecting cellulitis of the scalp or dissecting folliculitis also known as perifoliculitis capitis abscedens et suffodiens (PCAS), is a rare, severe and distinct dermatological disease. It most probably occurs because of follicular occlusion via hyperkeratosis, having the same mechanism of acnea conglobata and hidradenitis suppurativa Although the folliculitis and perifolliculitis may not be confined to the superficial follicle, this condition is classified with the superficial folliculitides because the accompanying necrosis is confined to the upper part of the follicle and the adjacent epidermis and superficial dermis, characteristically in a wedge-shaped area.218 There is fibrinoid necrosis of vessels at the apex of the wedge The histopathology is that of a typical scarring alopecia with perifollicular concentric fibrosis, mild perifollicular and perivascular lymphoid cell infiltrate, destruction of the follicular epithelium, naked hair shafts in giant cells, and, in terminal phases, follicular dropout (Figure 7B)

Perifolliculitis - an overview ScienceDirect Topic

  1. Perifolliculitis capitis abscedens et suffodiens is a rare and severe form of scalp folliculitis sometimes associated with acne conglobata, hidradenitis suppurativa and spinal arthritis (spondyloarthropathy). It most often affects black adult men but may rarely occur in white-skinned individuals, females, and children
  2. Perifolliculitis, on the other hand, is defined as the presence of inflammatory cells, usually lymphocytes, within the perifollicular tissues with focal extension into the adjacent reticular..
  3. Pseudofolliculitis barbae is a foreign-body inflammatory reaction surrounding ingrown facial hairs, which results from shaving. It can also occur on any body site where hair is shaved or plucked, including axilla, pubic area, and legs. It is also known as shaving rash or razor bumps. Folliculitis barbae and pseudofolliculitis barbae can co-exist

Perifolliculitis capitis abscedens et suffodiens (PCAS, or dissecting cellulitis of the scalp) is a therapeutically challenging suppurative scalp disease of unknown etiology. Spitzer first.. Dissecting cellulitis of the scalp, also termed perifolliculitis capitis abscedens et suffodiens, is characterized by painful fluctuant nodules and abscesses of the scalp connected by tortuous ridges or deep sinus tracts with cicatricial alopecia INFECTION with Trichophyton rubrum, a common dermatophyte, is most often a chronic infection of the feet and toenails.However, occasionally T rubrum infections may produce atypical clinical manifestations that may mimic other cutaneous diseases. A rarely reported manifestation of T rubrum infection is nodular granulomatous perifolliculitis (NGP), which may be easily misdiagnosed History Perifolliculitis capitis abscedens et suffodiens (PCAS) usually begins as a simple folliculitis, most often of the vertex and/or occiput, with clusters of perifollicular pustules rapidly.. Perifolliculitis capitis abscedens et suffodiens is a chronic inflammatory disease of the scalp characterized by the presence of large and small nodules that suppurate and intercommunicate by sinus formation. It may be more frequent in black males than in others (summary by McMullan and Zeligman, 1956). Acne inversa is a chronic inflammatory.

Dissecting cellulitis of the scalp (DCS), also known as perifolliculitis capitis abscedens et suffodiens or Hoffman's disease, is a rare cicatricial alopecia. Histology, as described by Scheinfeld, 8 reveals lesions with dense neutrophilic, lymphocytic, histiocytic, and plasma cellular infiltrate early on. A more chronic lesion will. Pathologically, this pattern corresponds to chronic folliculitis and perifolliculitis with a mixed infiltrate of lymphocytes, plasma cells, eosinophils, and neutrophils. Hair color change, another possible clinical pattern, is a consequence of interference with signals controlling melanogenesis, reversible during regrowth Perifolliculitis capitis abscedens et suffodiens (PCAS) is rare chronic, suppurative and inflammatory scalp disease.

Behçet's disease (BD) is a multisystemic, relapsing inflammatory disorder with an obscure etiology and pathogenesis. Diagnosis depends on the clinician's ability to identify a group of nonspecific mucocutaneous lesions, which also manifest in a number of other diseases. In recent years, there has been an increase in the studies focusing on the histopathological aspects of Behçet's. ETIOLOGIC DIAGNOSIS: Herpesviral perifolliculitis .

Folliculitis is defined histologically as the presence of inflammatory cells within the wall and ostia of the hair follicle, creating a follicular-based pustule.

Vesicular cutaneous lupus erythematosus Historical perspective. First recognized in the late 1960's, hidradenitis suppurativa was a unique skin disease described in Collies, Shetland sheepdogs and their crosses [15, 16].Since the early 1980's, the disease mentioned above was suspected to represent, in fact, bullous pemphigoid [17, 18] or erythema multiforme in these breeds [19, 20] Summary Perifolliculitis capitis abscedens et suffodiens (PCAS) is a rare scalp disease of unknown etiology which is hard to treat.It is often accompanied by scarring alopecia, acne conglobata, and recurrent fluctuant abscesses. PCAS belongs to the family of acne inversa (hidradenitis suppurativa). A 19‐year‐old man presented with PCAS for 2 years; multiple systemic antibiotic therapies.
