Acroqueratosis Verruciforme de Hopf: A propósito de un caso / Hopf Verruciform Acrokeratosis: A purpose of a case

RESUMEN La acroqueratosis verruciforme de Hopf (AV) es una enfermedad genética de transmisión autosómica dominante, una entidad poco frecuente, caracterizada, desde el punto de vista epidemiológico, por presentaruna distribución mundial, yafectara todas las razas, puede iniciarse en la infancia o de forma tardía en la edad adulta, con predominio del sexo masculino, caracterizada por pápulas queratósicas, aisladas, localizadas en dorso de manos, pies, brazos, codos y rodillas. El diagnostico se confirma con la histopatología existiendo en la actualidad varias alternativas terapéuticas. Se reporta el caso de un paciente, de sexo masculino, de 24 años de edad, quienpresenta una dermatosis de 8 años de evolución, caracterizada por lesiones papulosas queratósicasasimétricas, asintomáticas, localizadas en miembro superior derecho.

ABSTRACT Hopfverruciformacroqueratosis (VA) is a dominant autosomal transmitted genetic disease. It is an infrequent entity, characterized, from the epidemiological point of view, for presenting a worldwide distribution affecting all races, it begins in childhood or late in adulthood, with a predominance of males, caracterized by keratotic papules, isloted, located on the back, on the hands, feet, arms, elbows and knees. The diagnosis is confirmed with histopathology and there are currently several therapeutic alternatives. The case of a 24 year-old male that present a dermatological condition of 8 years of evolution, it is characterized by asimmetricalqueratotic papules lesions, located on the right upper limb, asymptomatics.

Non-familial Acrokeratosis Verruciformis of Hopf

Acrokeratosis verruciformis of Hopf is a rare genodermatosis with an autosomal dominant mode of inheritance. It is a disorder of keratinization, characterized by multiple, flat-topped, skin-colored keratotic lesions resembling plane warts typically observed on the dorsum of the hands and feet. Histopathologically, the lesion shows considerable hyperkeratosis, acanthosis, and papillomatosis, mimicking a "church spire", and a thickened granular layer. It arises in early life, often at birth or infancy. Herein, we report on a rare sporadic case of acrokeratosis verruciformis of Hopf. A 44-year-old Caucasian man presented with multiple, grouped, hyperkeratotic, whitish, flat papules on his shins and feet, which had been present for more than one year. Histopathological examination showed typical findings of acrokeratosis verruciformis of Hopf. Our case is unique in that the patient had no familial history of similar skin lesions.

Acrokeratosis Paraneoplastica with Adenocarcinoma of the Colon Treated with Topical Tretinoin

Acrokeratosis paraneoplastica, or Bazex syndrome, is one of the paraneoplastic syndromes. The characteristic skin lesions include palmoplantar keratoderma, psoriasiform skin lesions, hyperpigmentation, and nail dystrophy. The most common associated neoplasms are squamous cell carcinoma of the upper respiratory tract and other kinds of tumors with cervical lymph node metastasis. A 63-year-old woman presented with an 11 month history of hyperkeratotic lesions on the palms and soles. Ten months before she had been diagnosed with adenocarcinoma of the colon and undergone a left hemicolectomy. We report a case of acrokeratosis paraneoplastica associated with colon cancer which persisted after removal of the primary cancer, but resolved with topical tretinoin treatment.

A Case of Acrokeratosis Verruciformis of Hopf / 대한피부과학회지

Acrokeratosis verruciformis of Hopf is a localized disorder of keratinization affecting the distal extremities. It develops during infancy or early childhood with no sexual predilection. The disease seems to be inherited in an autosomal dominant fashion. We describe a 55-year-old male with multiple, flat-topped papules on the left dorsum of the hand. The histologic findings showed marked hyperkeratosis, acanthosis, papillomatosis of the epidermis and circumscribed elevation of the epidermis which characteristically resembled "church spires". This case is unusual in that the patient had late onset of the lesions and no family history of the condition.

Coexistence of Darier's Disease and Acrokeratosis Verruciformis of Hopf

Darier's disease and acrokeratosis verruciformis are inherited with the same pattern and they share similar clinical properties. We present a patient with both Darier's disease and acrokeratosis verruciformis. The patient had had brownish and skin-colored papules, initially on her face and neck, since the age of 25. Similar lesions had gradually spread to various parts of her body and lastly the dorsal aspect of her feet. On dermatological examination, brownish and skin-colored, 2 to 5 mm, keratotic papules were observed on her face, neck, both axillae, inframammary regions, and dorsa of the hands and feet. The nail examination revealed "V" shaped notches and longitudinal ridges on the fingers of both hands. The biopsy taken from the neck showed typical findings for Darier's disease. The biopsy from the dorsa of the left foot revealed the distinctive structures of acrokeratosis verruciformis. In this article the clinical and histopathological findings of these diseases are reviewed based on our patient.

A Case of Paraneoplastic Acrokeratosis (Bazex' Syndrome) / 대한피부과학회지

We report a case of paraneoplastic acrokeratosis(Bazex syndrome) occurring in a 70 year old man with small cell carcinoma of the lung. The skin lesions showed violaceous erythema and psoriasiform scaling of the face, aural helices, scalp, and palmoplantar regions with severe nail dystrophy, Histcipathological findings revealed hyperkeratosis, acanthosis and spongiosis in the epiderrnis, and lyrnphocytic infiltration in the upper dermis. He was treated with cis-diamine dichloroplanum(Cisplan), 4 o-demethy-l-o-epipodo- phyllotoxin (Etoposide ) and steroid onitrnent. But eight months later, he died of lung carcinoma.
