RESUMEN
We present two middle-aged patients with pruritic, crusted scalp erosions. Skin biopsy showed epidermal acantholysis with IgG and C3 intercellular deposits on direct immunofluorescence, leading to the diagnosis of localized pemphigus vulgaris. Resolution of the lesions without relapse occurred after low doses of oral prednisone and intralesional triamcinolone acetonide.

ABSTRACT: Darier disease (DD) is a rare genodermatosis. Literature on this topic is overwhelmingly dominated by case reports with rare clinical presentations, which have mentioned the histopathologic features briefly. The aim of this study was to document the histopathology of DD. Skin biopsies diagnosed as Darier disease based on clinicopathologic correlation over 12 years were reviewed for various epidermal and dermal features. There were 16 patients included, who most commonly presented in the third decade, with slight female predilection. The most common clinical presentation was hyperpigmented, hyperkeratotic, papules and plaques (91%), with 69% affecting the trunk. In addition to the classic suprabasal acantholytic clefts, we noted some unusual features: absence of parakeratosis (19%), a cornoid lamella-like pattern (62%), follicular acantholysis (13%) and multiple foci of involvement within a single biopsy (63%). Features such as the presence of dyskeratotic cells and minimal dermal lymphocytic infiltrates were concordant with previous literature. The limitation of this study was the small sample size. To conclude, pathologists must be aware of the variations in histopathology of Darier's disease, especially when challenged with atypical clinical presentations. The Darier-like pattern is met within several acantholytic diseases, and clinicopathologic correlation has the last word in arriving at a diagnosis.

Pemphigus is an autoimmune blistering disease with two major subtypes, pemphigus vulgaris (PV) and pemphigus foliaceus (PF). Although most patients with PV show oral lesions, cutaneous type PV (C-PV) is a rare subtype clinically characterized by predominant cutaneous involvement with no or subtle mucosal lesions. Patients with PF present with only skin involvement; they do not have mucosal lesions. Serologically, autoantibodies against desmoglein (Dsg) 3 and Dsg1 are observed in C-PV whereas PF is associated with anti-Dsg1 antibodies only. Herein, we describe three cases of pemphigus presenting with predominant skin lesions and no mucosal involvement despite high anti-Dsg 3 autoantibody levels in chemiluminescent enzyme immune assays (CLEIAs). In addition, anti-Dsg 1 autoantibodies were positive in patients 2 and 3, but negative in patient 1 based on CLEIAs. Histological examination of the skin showed suprabasal acantholysis in patients 1 and 2, and blister formation in the upper epidermis in patient 3. Histopathology of the oral membrane in patients 1 and 2 showed subtle acantholysis in the suprabasal layer. Thus, we diagnosed patients 1 and 2 as having cutaneous type PV and patient 3 as having PF. Ethylenediaminetetraacetic acid-treated enzyme-linked immunosorbent assay demonstrated a low proportion of anti-Dsg3 autoantibodies recognizing Ca2+ -dependent epitopes, antibodies against which are thought to be the main contributor to acantholysis. Thus, along with Dsg1 antibodies, weak anti-Dsg3 antibodies could induce acantholysis in the skin, but they are insufficient to induce mucosal lesions.

We report a mother and an adult son with Darier's disease. The mother, 76 years old and Japanese, had positivity for anti-desmoglein (Dsg)1 antibodies. She had erythema with hyperkeratosis and seborrheic and interstitial blistering. A high level of anti-Dsg1 antibodies was detected in the serum. Histopathological examination showed acantholysis and direct immunofluorescence testing revealed intercellular IgG and C3 deposition of the epidermis. Although she was diagnosed as having pemphigus foliaceus, the skin lesions slightly improved with immunosuppressive therapy. Her son, 47 years old, had similar skin lesions on the seborrheic and interstitial parts, but the anti-Dsg1 antibodies were negative in his serum. Histopathological examination showed acantholysis and dyskeratotic cells. Although Hailey-Hailey disease was first suspected, no mutation in the ATP2C1 was detected in either patient. Trio-exome analysis including the father showed a heterozygous c.2027C>A transition on exon 14 of ATP2A2, causing a replacement at amino acid 676 (p.Ala676Asp) in the mother and son only. The two patients were then diagnosed as having Darier's disease. Exome analysis further showed that a novel heterozygous missense mutation of DSG1 was identified only in the affected mother. Anti-Dsg1 antibody-positive Darier's disease is reported here for the first time. Very rare coexistence of Darier's disease and anti-Dsg1 antibody-positivity might be associated with this novel heterozygous DSG1 mutation. Experimental evidence is required to validate this hypothesis.

Dowling-Degos disease is a rare benign genodermatosis. It is characterized by lentiginous hyperpigmentation and reddish-brown papules and plaques. The flexor sides and intertrigines are often affected, but the clinical appearance may vary. Mutations in different genes are responsible for the clinical manifestation. While mutations in the keratin 5 (KRT5) gene favor a reticular distribution pattern, mutations in the POGLUT1 gene lead to a disseminated, papular clinical picture. Acantholytic variants of Dowling-Degos disease have historically been referred to as Galli-Galli disease, but our case study shows that the histopathological changes can vary even within a single patient. To date, no standardized therapy concept exists. The main focus is on keratolytic measures, with varying response. New therapeutic approaches using laser technology appear to be a promising treatment option.

BACKGROUND: Grover's disease (GD) is a relatively rare transient dermatosis that can be idiopathic or acquired. Acquired GD may occur secondary to internal triggers such as medications and malignancies and external factors such as friction. OBJECTIVE: The purpose of this report is to describe the clinical and histological presentation of drug-induced Grover's disease (DIGD) and discuss potential pathogenic mechanisms. METHODS: A systemic review of the literature was performed to identify medications implicated in DIGD. RESULTS: We identified 13 reports of patients with DIGD. Most patients presented with a papular or papulovesicular morphology involving the trunk and extremities. Pruritus was the most common symptom. The majority of the offending agents were cancer therapeutics. Discontinuation of the culprit medication was sufficient for rash clearance and symptom resolution in most cases. CONCLUSION: The overlap in morphology and associated symptoms in DIGD and GD makes the diagnosis of DIGD challenging and has potentially led to underdiagnosis. However, in cases of more extensive involvement and treatment recalcitrance, a drug-induced eruption should be considered.

Abstract A 55-year-old male presented with an eight-month history of erythematous papules and plaques with demarcated areas of spared skin on his trunk, upper extremities, neck, and face. Grover's disease is a rare, acquired disorder of unknown origin, which is classically characterized by the appearance of erythematous papules on the upper trunk that are usually transient. As in the present case, there are reports of atypical disease, with facial involvement, pityriasis rubra pilaris-like lesions, and a more chronic course.

Dowling-Degos disease is a rare autosomal dominant genodermatosis. It is characterized by acquired reticulate hyperpigmentation over the flexures, comedone-like follicular papules, and pitted perioral scars that usually develop during adulthood. Mutations in genes affecting melanosome transfer, and melanocyte and keratinocyte differentiation have been implicated in the pathogenesis of this disease. These genes include KRT5, POFUT1, POGLUT1 and, most recently, PSENEN. Dowling-Degos disease can be found in isolation or with other associated findings, most notably hidradenitis suppurativa. This condition belongs to a spectrum of conditions that all result in reticulate hyperpigmentation that at times are hard to distinguish from each other. The most closely linked entity is Galli-Galli, which is clinically indistinguishable from Dowling-Degos disease and can only be distinguished by the presence of acantholysis on microscopy. Unfortunately, Dowling-Degos disease is generally progressive and recalcitrant to treatment.

Acantholytic dyskeratotic acanthoma is a rare variant of epidermal acanthoma. It has a flat, plaque-like structure and is characterized microscopically by acantholysis and dyskeratosis. Eccrine syringofibroadenomatous hyperplasia is benign and likely reactive. It has recently been considered as a hyperplastic process affecting the eccrine ducts rather than the neoplasm because of its pathological heterogeneity and wide clinical associations. In this article, we present the case of 97-year-old Japanese women with a 10-mm wide, painful acantholytic dyskeratotic acanthoma accompanied by syringofibroadenomatous hyperplasia in the right femoral region. Although syringofibroadenomatous hyperplasia is known to occur as a reactive process with various dermatoses and cutaneous tumors, to date, there have been no reports of cases of acantholytic dyskeratotic acanthoma accompanying syringofibroadenomatous hyperplasia. Moreover, this case also includes the unusual finding of an increase in the mature sebocytes in the area of the syringofibroadenomatous hyperplasia.

INTRODUCTION: Transient acantholytic dermatosis has been frequently reported in patients with malignancies. While paraneoplastic cases have rarely been reported, most eruptions occur in the setting of chemotherapeutic agents. Management is based on limited data and primarily with topical steroids and topical emollients. A subset of patients exhibits recalcitrant disease and require alternate therapeutic approachesMethods: This systematic review consisted of identifying records in PubMed using the medical subject headings (MeSH) terms “chemotherapy” AND “Grover”, “chemotherapy” AND “Grover’s”, “cancer” AND “Grover”, “cancer” AND “Grover’s”, “malignancy” AND “Grover”, “malignancy” AND “Grover’s”, as well as a free text search for “Grover” OR “Grover’s” OR “Grover disease” OR “Grovers disease” OR “Grover’s disease” OR “transient acantholytic dermatosis” OR “transient acantholytic” to identify case reports, case series, systematic reviews, review articles, meta-analyses, clinical trials, brief commentaries, and original articles. The titles and abstracts of all results were reviewed. Full texts of relevant results were then read in their entirety and applicability was determined. RESULTS: Overall, Grover disease has rarely been reported in the setting of malignancy. When it occurs, it is generally in the setting of chemotherapy use. Chemotherapy-associated Grover disease is reported most frequently in association with cytotoxic chemotherapies, followed by small molecule inhibitors. The first line treatment for this complication is the use of topical agents. When these provide inadequate relief, alternate therapies have been rarely reported, with novel treatments proposed based on the type of chemotherapy agent and its mechanism of action. CONCLUSIONS: Chemotherapy-associated Grover disease is an uncommon complication of cancer treatment. While most cases of chemotherapy-associated Grover disease can be treated with topical steroids and topical emollients, certain cases require a more specialized approach. This could include adjuvant adjuvant therapies, or novel treatments that are directly related to the mechanism of action of the chemotherapy involved.

RATIONALE: Acantholytic squamous cell carcinoma (ASCC) is an uncommon histopathologic variant of squamous cell carcinoma (SCC), which is the most common malignancy of the oral cavity. Though ASCC showed poor prognosis, the exact diagnosis is challenging. PATIENTS CONCERNS: A 59-year-old female patient with 1-month long symptoms of pain and burning sensation in the right maxilla. DIAGNOSES: Incisional biopsy in the maxilla established the pathologic diagnosis of SCC. INTERVENTION: The patient underwent mass resection with near total maxillectomy. OUTCOMES: The final diagnosis through the microscopic examination was ASCC. Palliative chemotherapy was done to relive the symptoms after the recurrence, however, the patient died of the disease at 8 months after her initial presentation. LESSONS: Special attention should be paid to this variant of SCC because most patients with ASCC have a very poor prognosis.
