Persistent acantholytic dermatosis related to actinic damage

Grover's Disease Association with Cutaneous Keratinocyte Cancers: More than a Coincidence?

Better mechanistic understanding of desmosome disruption and acantholysis in Grover's disease (GD) may improve management of this disease. Recent molecular studies highlighted promising pathways to be explored by directly comparing GD and selected features of associated skin diseases. The association between GD and cutaneous keratinocyte carcinomas, the most prevalent non-melanoma skin cancers (NMSC), is not completely characterized. To review the medical literature regarding GD-associated cutaneous keratinocyte cancers, focusing on molecular features, pathophysiological mechanisms, and disease associations, to help guide future research and patient management. GD has been associated with a variety of skin conditions, but its association with skin cancers has been rarely reported. Between 1983 and 2024, only nine scientific papers presented data supporting this association. Interestingly, we found that GD may mimic multiple NMSCs, as few authors reported GD cases misdiagnosed as multiple cutaneous squamous cell carcinomas for more than 4 years or the presence of superficial basal cell carcinoma-like areas associated with focal acantholysis. In conclusion: (a) GD may be an imitator of multiple NMSCs, and (b) the relationship between GD and NMSCs may reveal promising pathways for the mechanistic understanding of desmosome disruption and acantholysis in GD and may even lead to its reclassification as a distinctive syndrome.

Clinical features and treatments of transient acantholytic dermatosis (Grover's disease): a systematic review

Grover's disease (GD) is an itchy acantholytic disorder occurring on the trunk of middle-aged men. Based on the best evidence, this study aimed to provide a summary of the clinical characteristics, disease course and treatments of GD. A systematic review was performed according to PRISMA guidelines for original articles published between 01.01.1970-08.15.2019, assessing clinical features and/or any type of intervention for GD. A total of 263 articles were retrieved, and 116 original reports that were deemed relevant and satisfied the inclusion criteria were included in the analysis (88 case reports, 26 case series and two retrospective reviews). From these articles, 317 patients were identified, with a male-to-female ratio of 3.95. The mean age was 59 years (range 11-92). Typical lesions were itchy papules and vesicle-papules, generally located on the trunk. Spontaneous resolution within one week to eight months was described in 42 % of cases. Topical corticosteroids (TCSs) were the most frequent treatment (response rate of 70 %) followed by systemic retinoids and corticosteroids with response rates of 86 % and 64 %, respectively. According to the results of this review, TCS appears to be the most frequently employed treatment, and we suggest TCS as first-line therapy. Second-line treatments could include systemic retinoids or systemic corticosteroids.

Seasonal variation of transient acantholytic dyskeratosis (Grover's disease)

BACKGROUND

Grover's disease (GD), or transient acantholytic dermatosis, is a pruritic, papulovesicular eruption characterized histopathologically by acantholysis with or without dyskeratosis. The origin of GD is unknown. Suggested causes include sweating, heat, immobilization occlusion, external beam and ultraviolet radiation, and xerosis. GD has also been found to occur in association with other diseases.

OBJECTIVE

Our aim was to assess whether GD exhibits seasonal variation and, if so, to determine whether any inferences can be drawn from its seasonal variation regarding its cause.

METHODS

We identified 385 patients who fulfilled both clinical and histopathologic criteria for GD among 423,106 patients diagnosed at the Ackerman Academy of Dermatopathology in New York City during the period from July 1, 1999 through June 30, 2004. By design, no hospitalized patients were studied.

RESULTS

A diagnosis of GD was given to 0.09% of biopsy specimens at the Ackerman Academy of Dermatopathology. GD was diagnosed approximately 4 times more commonly in winter than in summer, although the number of biopsies was constant. The average age of GD patients was 64 years with a male/female ratio of 1.95:1. The most common histopathologic type of GD was pemphigus vulgaris. GD was suspected clinically in 54% of patients.

LIMITATIONS

This study did not assess hospitalized patients with GD or GD patients who lived outside the northeastern United States. Because the data assessed resided in a commercial dermatopathology laboratory, patients assessed in almost all cases had insurance coverage. Patients without insurance likely were not included in the study.

CONCLUSIONS

The diagnosis of GD constitutes a higher proportion of biopsies in the winter than in the summer and therefore, by inference, occurs more frequently in the winter. In the winter, elderly men whose skin is naturally xerotic sweat less and are exposed to low ambient humidity. Rather than being caused by sweating and heat, GD arises against a backdrop of an intact but xerotic epidermis with decreased sweat production and is likely related to impaired epidermal integrity.

Persistent acantholytic dermatosis of the lip related to solar damage

We describe the case of a 70-year-old woman with persistent acantholytic dermatosis. The peculiarity of the case lies in the unusual localization of this dermatosis on the lower lip. A possible relationship with chronic solar damage is discussed.

Effective treatment of persistent papular acantholytic dermatosis with cyclosporine

We describe a patient with persistent papular acantholytic dermatosis provoked by phototoxic reaction to his usual perfumed soap and shaving foam. Therapy with systemic and topical corticosteroids failed to improve the patient. Treatment with cyclosporine was found to be effective.

Successful treatment of transient acantholytic dermatosis with systemic steroids

A sixty-year-old man, developed 2-5 mm sized, hyperemic, itchy papules, vesicles, erosions and crusts on hyperemic base on his chest, abdomen, back, gluteal region, and proximal sites of his upper and lower extremities. The direct and indirect immunoflurescence tests were negative. Histology revealed extensive acantholysis in the epidermis in the following forms: pemphigus vulgaris-like suprabasal acantholysis, Darier-like acantholytic dyskeratosis with corps ronds, Hailey-Hailey-like suprabasal clefts, and pemphigus foliaceus-like superficial acantholysis with spongiosis. Using systemic steroids, topical drying, and reepithelising therapy, the patient was cured. He was symptom-free the first, fourth, and thirteenth months after finishing steroid therapy. We review the literature and the new subdivision of the disease according to the histological and clinical features.

Transient acantholytic dermatosis (Grover's disease): a global perspective

Twenty-six years have passed since Grover first described transient acantholytic dermatosis. Since then, the concept of Grover's disease has been expanded to include persistent acantholytic dermatoses as well. Although its origin remains unknown, it may result from an isomorphic response to excessive heat, sweating, or xerosis. It is currently classified as a nonfamilial, non-immune-mediated, acantholytic disorder.

A rare presentation of acantholytic dyskeratosis

We describe an elderly woman who presented with numerous papular, keratotic lesions on the scalp. Histology of a biopsy specimen revealed epidermal invaginations, with large keratotic plugs, at the sites of hair follicles. In addition, there was acantholytic epidermal cell separation at a suprabasal level, and a large number of corps ronds were present above the split. It is likely that this case represents a rare presentation of acantholytic dyskeratosis. The relationship to other conditions which show acantholysis and dyskeratosis histologically is discussed.

A case of bullous transient acantholytic dermatosis

We report a case of a bullous variant of transient acantholytic dermatosis in a 59-year-old female. Each bullous lesion lasted several weeks and healed without scarring. The lesions were migratory and recurrent without a cleared period. Histopathologic examination revealed an intraepidermal vesicle low in the epidermis. The lesions cleared after 2 months of isotretinoin therapy.

Transient acantholytic dermatosis induced by recombinant human interleukin 4

BACKGROUND

Interleukin 4 is one of many cytokines under investigation about its possible role in the pathogenesis and treatment of disease. Transient acantholytic dermatosis is of uncertain origin. It has not previously been linked to drug ingestion and is generally not believed to have an immunologic basis.

OBJECTIVE

Our purpose was to describe the clinical characteristics and histologic features of a cutaneous eruption caused by interleukin 4.

METHODS

Three patients in whom an eruption developed after they received intravenous recombinant human interleukin 4 were examined and biopsy specimens were evaluated.

RESULTS

These patients had a pruritic papulovesicular eruption that was consistent, both clinically and histologically, with transient acantholytic dermatosis. None of the other conditions believed to precipitate transient acantholytic dermatosis was present in our patients.

CONCLUSIONS

This is the first report of a cutaneous side effect of interleukin 4. This may be antibody-mediated or related to increased production of tissue-type plasminogen activator.

Benign persistent papular acantholytic and dyskeratotic eruption: a case report and review of the literature

We report a case of a 35-year-old female with a persistent pruritic acantholytic and dyskeratotic eruption on the chest and vulva. The light and electron microscopic studies showed suprabasal epidermal clefting with acantholysis and dyskeratotic cells. We suggest that the most appropriate term for this case is that of benign persistent papular acantholytic and dyskeratotic eruption.
