We describe 3 outbreaks of superficial dermatitis caused by bovine herpesvirus 2 (BoHV-2) in dairy breed calves. Clinically, all of the affected calves were 12-26 d of age, had alopecia and crusts on the face and ears, and were non-pruritic and afebrile. Affected animals recovered spontaneously without any treatment within 2-4 wk after onset of clinical signs based on 1 herd with follow up. Histologic examination of all skin crust or tissue samples identified neutrophilic inflammation, mild hyperkeratosis, multinucleate syncytial cells, and intranuclear inclusion bodies in the syncytial cells...

Allergic contact stomatitis (ACS) is an oral mucosal immunoinflammatory disorder variably characterized clinically by erythematous plaques, vesiculation, ulceration, and/or hyperkeratosis and by pain, burning sensation, or itchiness. ACS is brought about by a T cell-mediated, delayed hypersensitivity immune reaction generated by a second or subsequent contact exposure of an allergen with the oral mucosa, in a genetically susceptible, sensitized subject. Lichenoid contact reaction is a variant of ACS brought about by direct contact with the oral mucosa of certain metals in dental restorations...

Pseudoepitheliomatous keratotic and micaceous balanitis (PKMB) is an uncommon premalignant condition involving the glans penis. We report the case of an 86-year-old man who presented with phimosis and pain on retracting his foreskin. He had previously undergone circumcision, which revealed a hyperkeratotic plaque with thin mica-like scales involving his glans penis. Histology of the lesion showed hyperkeratosis, parakeratosis, epidermal acanthosis and papillomatosis with no evidence of dysplasia. Immunohistochemistry for human papillomavirus was negative...

Palmoplantar keratoderma (PPK) is a dermatosis that presents as hyperkeratosis of the palms and soles. It may be acquired or heritable. Acquired PPK often occurs as a paraneoplastic response as well as a stigma of other dermatoses. We report a rare case of a 72-year-old woman with acquired PPK secondary to metastatic uterine adenocarcinoma. We also review other rare cases of cutaneous paraneoplasia secondary to uterine cancer and describe the salient features of acquired PPK. Acquired PPK most commonly presents as a paraneoplastic response to visceral malignancies that include localized esophageal, pulmonary, urinary/bladder, and gastric carcinomas, as well as myeloma...

Mechanic's hands is a well-characterized manifestation of select idiopathic inflammatory myopathy (IIM) syndromes. Less well characterized is the hyperkeratosis of the toes and plantar surface of the feet that can also accompany these disorders. We aim to describe common pedal signs in the context of IIM, and suggest that it may be another key feature in the presentation of these syndromes. A cohort of 2145 myositis patient charts gathered since 2003 were retrospectively reviewed using the key search terms "mechanic's feet" and/or "mechanic's foot...

BACKGROUND: Podoconiosis affects an estimated 3 million people in Ethiopia with a further 19 million at risk. Volcanic soil and pathogens enter skin breaches in the feet causing inflammation, lymphoedema and hyperkeratosis. There is no robust evidence on optimal podoconiosis skin care regimens to improve SBF. OBJECTIVES: To evaluate the effectiveness of a new, low-cost, evidence-based intervention to improve SBF in the lower limbs of those with podoconiosis. METHODS: A randomized control trial (RCT) was conducted over 3 months in two podoconiosis clinics (n=193)...

Centella asiatica has potent antioxidant and anti-inflammatory properties. However, its anti-dermatitic effect has not yet been reported. In this study, we investigated the anti-dermatitic effects of titrated extract of Centella asiatica (TECA) in a phthalic anhydride (PA)-induced atopic dermatitis (AD) animal model as well as in vitro model. An AD-like lesion was induced by the topical application of five percent PA to the dorsal skin or ear of Hos:HR-1 mouse. After AD induction, 100 μL of 0.2% and 0.4% of TECA (40 μg or 80 μg/cm²) was spread on the dorsum of the ear or back skin three times a week for four weeks...

PURPOSE: Poikiloderma with Neutropenia (PN) is inherited genodermatosis which results from a biallelic mutation in the USB1 gene (U Six Biogenesis 1). PN, first described in Navajo Native Americans, is characterized by early onset poikiloderma, pachyonychia, palmo-plantar hyperkeratosis, and permanent neutropenia. This condition results in frequent respiratory tract infections during infancy and childhood. From 2011 to 2013, four cases of PN were diagnosed in Morocco. In this paper, we report the first four cases of PN diagnosed in Morocco, out of three unrelated consanguinous families...

Warty dyskeratoma is an uncommon entity characterized by a solitary keratotic papule or nodule usually located in the head and neck of young adults. The histopathology shows a pattern of acantholytic dyskeratosis. We report a 32-year-old man who presented pain, serous exudation, a distal onycholysis with subungual hyperkeratosis, and roundish erythronychia in the nail plate of his left first toe 2 years ago. A histopathologic diagnosis of subungual warty dyskeratoma was made. When dealing with focal acantholytic dyskeratosis several differential diagnoses should be considered including Darier's disease, transient focal acantholytic dyskeratosis or Grover disease, and Hailey-Hailey disease...

BACKGROUND: Oral lichen planus (OLP) is a T-cell-mediated inflammatory disease; however, its exact etiology is unknown. Hyperkeratosis is often observed in OLP lesions. Previous studies have revealed the localization of Mycoplasma salivarium in the epithelial cells of oral leukoplakia with hyperkeratosis. Herein, we investigated the presence of M. salivarium in OLP tissue by immunohistochemistry to determine the causative factor of OLP. METHODS: Forty-one formalin-fixed, paraffin-embedded samples obtained from 31 patients with OLP were examined...
