An Atypical Localized Form of Hidradenitis Suppurativa of the Jawline and Neck Mimicking Severe Cystic Acne on Presentation

Ectopic presentation of hidradenitis suppurativa

Hidradenitis suppurativa (HS) is a chronic inflammatory disease involving primarily intertriginous skin areas. Ectopic HS lesions are a reported phenomenon that is not fully understood. We present a case report of a 66-year-old patient with painful symmetric ulcerated plaques on the posterior surface of the ankles and lower lip. In addition, we performed a systematic review on ectopic HS by conducting an electronic literature search to identify relevant contributions. Inclusion criteria included English-language and full texts only using PubMed, Embase, and the Cochrane Database. We found 22 eligible contributions reporting on a total of 58 patients. Most of the patients were men who had lesions on the head and neck region. The reviewed cases share common features with HS and may be considered disorders of follicular occlusion.

Cervicofacial hidradenitis suppurativa: A case report and literature review

Hidradenitis suppurativa (HS) is a chronic inflammatory condition of the apocrine glands primarily affecting the axillae, perineum, and inframammary regions. It is characterized by painful, inflamed cutaneous lesions causing nodules, sinus tracts, and abscesses. Cervicofacial HS is an atypical presentation of HS in the head and neck region and is scarcely reported in the literature. We present a 34-year-old male who developed a large facial swelling overlying the left inferior mandibular border. Management included surgical incision and drainage, antibiotic therapy, followed by infliximab (Remicade). The purpose of this case report was to highlight the presentation, pathophysiology, interdisciplinary approach to treatment and follow-up of patients with cervicofacial HS, and finally, review the cervicofacial HS literature.

Case report of hidradenitis suppurativa localized to the face in an HIV patient

Hidradenitis suppurativa is a chronic, debilitating inflammatory skin disease. Case reports of individuals with hidradenitis suppurativa presenting exclusively on the face, as well as reports of individuals with HIV and hidradenitis suppurativa, are rare. Here, we present the case of an HIV-positive man who presented with hidradenitis suppurativa localized only on his face. We also review facial hidradenitis suppurativa and hidradenitis suppurativa in HIV patients.

The role of biologic treatment in special scenarios in hidradenitis suppurativa: Facial and nape phenotype, dissecting cellulitis of the scalp, and lymphedema

Hidradenitis suppurativa (HS) is a chronic inflammatory disorder affecting the hair follicle which typically affects the axilla, inguinal, submammary, and perianal areas. Atypical HS, such as facial HS, dissecting cellulitis of the scalp (DCS), nape HS, and HS lymphedema has also been described. There is scarce evidence about the treatment of atypical HS. To describe the efficacy of biologic drugs and adjuvant therapeutic interventions used in patients with atypical HS who had an inadequate response to systemic antibiotics. Prospective case series study of patients with atypical HS (facial HS, DCS, nape HS, and HS lymphedema) treated with biologic drugs in a HS Clinic setting. Disease activity indexes, sociodemographic, clinical, and safety variables were collected. Two patients met criteria for Facial HS, three met criteria for DCS/nape HS and three patients met criteria for HS lymphedema. Patients with facial HS achieved rapid improvement without requiring other therapies. Patients with DCS, nape HS, and HS lymphedema showed variable response, with decrease of activity indexes, and requiring adjuvant treatments. Biologic drugs are useful in the management of special HS locations. In the case of facial HS, biologic therapy seems to be quite effective as monotherapy. In the cases of DCS, HS lymphedema and nape HS, treatment combination or intensification may be needed.
