A Case of Extensive Grover’s Disease in a Patient with a History of Multiple Non-Melanoma Skin Cancers

We report on a 69-year-old man who presented with itching and erythematous papules on his torso and extremities, which were resistant to topical therapy with antibiotics and steroids. Physical examination revealed multiple erythematous papules on his back, neckline, and lower extremities. The lesions had appeared 4 years earlier and usually worsened with heat or extensive sweating. Histopathology of previous skin biopsies had shown multiple cutaneous squamous cell carcinomas or was non-conclusive. Thus, a re-biopsy was performed, revealing acanthosis and focal acantholytic dyskeratosis. These clinical and anamnestic findings lead to the diagnosis of extensive Grover’s disease (GD). Oral therapy with isotretinoin 30-mg QD led to the regression of the skin lesions. Topical adapalene, as well as topical corticosteroids, were later prescribed for maintenance therapy.

A Rare Case of Transient Acantholytic Dermatosis (AKA. Grover’s Disease) with Concomitant Pediculosis Pubis: An Atypical Presentation and First Documented Case Report

A 66-year-old male presented with a one-month history of persistent pruritic eruptions distributed mainly on the trunk. A punch biopsy from the left upper abdomen revealed focal acantholytic dyskeratosis with mixed inflammatory infiltrate in the dermis composed of numerous eosinophils. Grover’s disease was diagnosed based on the clinical and histopathological findings. Appropriate treatment was initiated but failed to relieve symptoms of itchiness. A further investigation of the hair follicles under mineral oil preparation revealed an infestation of pediculosis pubis. Subsequent treatment with Ivermectin and permethrin cream led to the complete resolution of his symptoms. This case report highlights an unusual and first documented case of Grover’s disease with a concomitant infestation of pediculosis pubis. To date, no reported cases in the literature have associated Grover’s disease with pubic lice infestation. However, there are three reported cases of concurrent scabies and Grover’s disease in the literature. This rare case underscores the clinical value in further investigating treatable underlying conditions in patients with suspected transient acantholytic dermatosis.

Grover’s disease: a rare bullous dermatosis spontaneously regressing

Grover's diseaseis an itchy acantholytic disorder occurring on the trunk of middle-aged men. It is a transient dermatosis of unknown cause manifesting clinically as a papular skin eruption located usually on the anterior chest and abdomen and histologically with dyskeratosis and acantholysis. This disease has occasionally been reported in patients with chronic renal failure, some infections, hematological malignancies, and many other anomalies. We report herein a new case of Grover's disease that developed in a female patient after a fever episode.

A Case of Grover’s Disease Secondary to Brodalumab Therapy for Psoriasis

Background: Grover’s disease has been associated with a number of medications including sulfadoxine-pyrimethamine, recombinant interleukin (IL)-4, ipilimumab, and BRAF inhibitors. To our knowledge, Grover’s disease has not been reported in association with interleukin-17 inhibitors. Case Description: A 47-year-old female with plaque psoriasis developed Grover’s disease 3 months following initiation of brodalumab. Discontinuation of brodalumab and initiation of certolizumab pegol and methotrexate led to resolution of her rash. Conclusion: This case highlights Grover’s disease as a potential adverse effect of brodalumab therapy. In patients who develop Grover’s disease with brodalumab, modification of therapy may be considered due to the bothersome nature of the rash.

Skin Manifestations in COVID-19: Prevalence and Relationship with Disease Severity

Background: Data on the clinical patterns and histopathology of SARS-CoV-2 related skin lesions, as well as on their relationship with the severity of COVID-19 are limited. Methods and Materials: Retrospective analysis of a prospectively collected cohort of patients with SARS-CoV-2 infection in a teaching hospital in Barcelona, Spain, from 1 April to 1 May 2020. Clinical, microbiological and therapeutic characteristics, clinicopathological patterns of skin lesions, and direct immunofluorescence and immunohistochemical findings in skin biopsies were analyzed. Results: Fifty-eight out of the 2761 patients (2.1%) either consulting to the emergency room or admitted to the hospital for COVID-19 suspicion during the study period presented COVID-19 related skin lesions. Cutaneous lesions could be categorized into six patterns represented by the acronym “GROUCH”: Generalized maculo-papular (20.7%), Grover’s disease and other papulo-vesicular eruptions (13.8%), livedo Reticularis (6.9%), Other eruptions (22.4%), Urticarial (6.9%), and CHilblain-like (29.3%). Skin biopsies were performed in 72.4%, including direct immunofluorescence in 71.4% and immunohistochemistry in 28.6%. Patients with chilblain-like lesions exhibited a characteristic histology and were significantly younger and presented lower rates of systemic symptoms, radiological lung infiltrates and analytical abnormalities, and hospital and ICU admission compared to the rest of patients. Conclusion: Cutaneous lesions in patients with COVID-19 appear to be relatively rare and varied. Patients with chilblain-like lesions have a characteristic clinicopathological pattern and a less severe presentation of COVID-19.
