Transient acantholytic dermatosis

A 79-year-old man with a recent diagnosis of acute myeloblastic leukemia received induction chemotherapy with daunorubicin and cytarabine, plus moxifloxacin and fluconazole prophylaxis. Approximately 2 weeks later, an asymptomatic eruption appeared on his trunk. He then developed a neutropenic fever and was started on aztreonam, vancomycin, voriconazole, and amikacin and was transferred to our facility from an outside hospital. Micafungin was subsequently added, and the patient defervesced within a few days...

A total of 3 cases of pseudoherpetic transient acantholytic dermatosis (Grover disease) are presented, followed by a brief review of prior reports. All 3 patients were above the age of 60 and presented with a pruritic eruption composed of papules with or without vesicles distributed on the trunk. For all 3 patients, the clinical differential diagnosis included drug eruption but did not include Grover disease; in 1 patient, the clinical impression included herpesvirus infection. Similar histologic and immunohistochemical findings were demonstrated in all 3 cases...

BACKGROUND: Dermatologic toxicity is an important adverse effect of immune checkpoint inhibitors targeting cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) and programmed cell death 1 receptor (PD-1) or PD ligand 1 (PD-L1). Skin toxicity most commonly includes a maculopapular erythematous rash and pruritus. Rarely life threatening complications such as Steven's Johnson syndrome or toxic epidermal necrolysis may occur. CASE PRESENTATION: Here we report the uncommon event of a drug-induced transient acantholytic dermatosis (Grover's disease) in a 73-year-old Caucasian male treated with ipilimumab for metastatic melanoma...

Cutaneous eruptions in recipients of allogeneic haematopoietic stem cell transplantation (AHSCT) are frequent, and common aetiologies include graft-versus-host disease (GVHD), drug reactions, viral infections and engraftment syndrome. Transient acantholytic dermatosis or Grover's disease has been described in oncology patients and it is rarely reported after AHSCT. However, this benign and self-limiting condition should be histologically distinguished from other, more serious entities, mainly stage IV GVHD, in order to avoid inappropriate treatment with corticosteroids and intensive immunosuppression...

BACKGROUND: Multinucleated giant cells in the epidermis can either be epithelial or histiocytic. Epithelial multinucleated giant cells are most often associated with herpes virus infections. PURPOSE: To review the histologic differential diagnosis of conditions with epithelial and histiocytic multinucleated giant cells-since multinucleated giant cells in the epidermis are not always pathognomonic of a cutaneous herpes virus infection-and to summarize dermatoses in which herpes virus infection has been observed to coexist...

Although Malassezia yeasts are a part of the normal microflora, under certain conditions they can cause superficial skin infection, such as pityriasis versicolor (PV) and Malassezia folliculitis. Moreover the yeasts of the genus Malassezia have been associated with seborrheic dermatitis and dandruff, atopic dermatitis, psoriasis, and, less commonly, with confluent and reticulated papillomatosis, onychomycosis, and transient acantholytic dermatosis. The study of the clinical role of Malassezia species has been surrounded by controversy due to the relative difficulty in isolation, cultivation, and identification...

IMPORTANCE: Pruritus is a common problem among elderly people and, when severe, causes as much discomfort as chronic pain. Little evidence supports pruritus treatment, limiting therapeutic possibilities and resulting in challenging management problems. OBJECTIVES: To present the evidence on the etiology, diagnosis, and treatment of pruritus in the elderly and, using the best available evidence, provide an approach for generalist physicians caring for older patients with pruritus...

A 48-year-old man with a newly diagnosed acute myeloid leukemia developed purpuric rash on day 6 after chemotherapy. Skin biopsy on day 8 demonstrated Grover disease. Triamcinolone treatment started on day 10 with subjective improvement on day 15. Initial FDG PET/CT on day 12 demonstrated rarely seen diffuse skin uptake that was interpreted as technical artifact and repeated on day 16. Accurately reviewing both PET and CT imaging would prevent confusion between diffuse cutaneous hypermetabolic activity and a technical artifact...

Grover's disease (GD) is a transient or persistent, monomorphous, papulovesicular, asymptomatic or pruritic eruption classified as non-familial acantholytic disorder. Contribution of autoimmune mechanisms to GD pathogenesis remains controversial. The purpose of this study was to investigate antibody-mediated autoimmunity in 11 patients with GD, 4 of which were positive for IgA and/or IgG antikeratinocyte antibodies by indirect immunofluorescence. We used the most sensitive proteomic technique for an unbiased analysis of IgA- and IgG-autoantibody reactivities...

Grover's disease is a transient acantholytic dermatosis of unknown cause, manifesting clinically as a papular skin eruption that is usually located on the anterior chest and abdomen. Histologically characterized by an acantholytic pattern, it has been associated with numerous disorders, including hematologic malignancies, chronic renal failure, and HIV infection, as well as with chemotherapy and bone marrow and/or kidney transplant. Evaluation of followup and treatment is often complicated by spontaneous remission and the occasionally fluctuant course of the disease...

We present the case of a 79-year-old woman with a history of breast cancer who developed Grover disease (transient acantholytic dermatosis) following initiation of an aromatase inhibitor, anastrozole, as adjunctive treatment of her breast cancer. A number of drugs have been associated with this condition; however, to our knowledge, this case is the first report of anastrozole-induced Grover disease.

Galli-Galli disease is considered as a rare variant of Dowling-Degos disease, sharing the same clinical features of reticulate hyperpigmentation of the flexures. Histopathologically, there is acantholysis and suparabasal lacunae. Grover disease (transient acantholytic dermatosis) is a transient dermatosis which clinically presents as an eruption of erythematous excoriated papules located on the trunk and histologically with dyskeratosis and acantholysis. Grover disease has occasionally been reported in patients with chronic renal failure, human immunodeficiency virus infection, hematological malignancies, bone marrow allotransplantation, and renal transplantation...

Grover's disease (GD), or transient acantholytic dermatosis, is a persistent recurrent dermatosis that usually occurs in men older than 50 years. Rare cases of GD and hematologic malignancy in the same cutaneous biopsy specimen have been reported. We report a case of GD in association with leukemia cutis. A 72-year-old man with a history of myelodysplastic syndrome presented with numerous pruritic papules on the torso, which were clinically diagnosed as GD. A skin biopsy revealed foci of suprabasal acantholysis and dyskeratosis consistent with GD and dense aggregates of mononuclear atypical cells in the superficial dermis consistent with leukemia cutis...

Grover disease (GD) is a rather common papular pruritic dermatosis that can be transient, persistent, or asymptomatic. The microscopic diagnosis of clinically suspected lesions can be challenging because GD can adopt different patterns, and involved areas are generally admitted to be mostly focal. The histopathologic hallmark of the disease is acantholysis, frequently combined with dyskeratosis, which confers the lesions an appearance similar to Darier disease, Hailey-Hailey disease, or pemphigus. Eczematous features can be observed as well...

Grover disease, also known as transient acantholytic dermatosis, is a papulovesicular rash of the upper trunk, generally among older white males; it is usually pruritic but temporary. Grover disease is characterized by 4 different acantholytic histologic patterns, and it has been associated with numerous disorders, including hematologic malignancies. Follow-up and treatment are often difficult to evaluate secondary to the spontaneous remittance and occasional fluctuant course of the disease. Our objective will be to discuss the diagnostic considerations of Grover disease and focus on the postulated pathogenesis, including concurrent disorders and the role of the pathologist in examining skin biopsies of this nonhereditary vesicobullous disorder...

BACKGROUND: Acantholytic disorders, including pemphigus vulgaris, chronic benign familial pemphigus (Hailey-Hailey disease, superficial pemphigus), Darier disease, and Grover transient acantholytic dermatosis, as well as other vesiculo-bullous disorders, including bullous pemphigoid, epidermolysis bullosa, and atopic dermatitis, are prone to florid infections by herpes simplex virus (HSV)-I and -II, and, more rarely, by varicella-zoster virus (VZV). As these infections are difficult to recognize clinically and histologically, their frequency remains unknown...

Galli-Galli disease is a rare variant of the genodermatosis Dowling-Degos disease with the histologic finding of acantholysis. We present the case of a patient who presented with reticulated pigmentary changes in the flexures as well as a pruritic papular eruption and histologic features consistent with Galli-Galli disease. A literature search revealed 3 previous case reports of Galli-Galli disease. These case reports were reviewed and summarized, and the clinical and histologic presentations were compared with those of our patient...

Grover disease, or transient acantholytic dermatosis, chiefly affects the upper part of the trunk in men older than 40 years. Lesions may last for weeks, months, or years, and often are accompanied by intense pruritus. Some patients respond to topical steroid treatment but many do not. This article reports major or total resolution of Grover disease in 6 of 9 patients following topical application of a triple antibiotic ointment. It also proposes using a case registry as a way of further investigating the efficacy of this treatment so that dermatologists may participate...
