INTRODUCTION Psoriasis is a common, chronic dermatologic disease. Cases affecting the oral mucous membranes are rarely reported in the international literature, in particular tongue lesions are hardly ever documented. MATERIAL AND METHODS This article presents a 61 year old patient with persistent whitish lesion on his tongue. Biopsy specimens from mid surface and tip of the tongue were taken...

The clinical diagnosis of psoriasis is relatively easy, especially when the lesions consist of erythematous, silvery white scaly, sharply demarcated, indurated plaques, distributed symmetrically on the extensor surfaces of limbs, the lower back and the scalp. These clinical features reflect the histopathological findings observed in active lesions, characterized by parakeratosis, acanthosis of ...

Chemotherapy-induced inflammation of actinic keratosis can present in patients with subclinical actinic keratoses that become erythematous and pruritic within weeks of initiating systemic chemotherapy. The reaction is limited to sun-exposed areas and, classically, histologic findings of parakeratosis and epidermal necrosis with keratinocyte nuclear pleomorphism are present. Exuberant reactions ...

Human papillomavirus (HPV) survives by reactivating DNA replication in post-mitotic cells. In the present study, we describe a mouse model of HPV-dependent disease. In these mice, DNA synthesis is activated in suprabasal keratinocytes, leading to acanthosis, parakeratosis and enhanced desquamation. The full-length E6/E7 transcript and two alternately spliced products are produced and in most li...

Lymphomatoid keratosis (LK) is considered to be a rare variant of cutaneous lymphoid hyperplasia, with epidermotropism. We herein report a case of LK which developed on the abdomen of an elderly Korean woman. A 60-year-old woman presented with a 10-year history of a pruritic, solitary, brown to black plaque on the abdomen. Histopathologically, the specimen showed hyperkeratosis, parakeratosis, ...

: Psoriaisis is a common papulosquamous condition seen by the dermatologists. It can involve skin and nails. There are many sub types of Psoriasis with various clinical, histopathological dermoscopic features. In this study we intend to epidemiological, features Chronic Plaque (CPP). A total 45 patients CPP, above age 18 years who qualified inclusion exclusion criteria were included in study. p...

AIMS The viral etiology of certain types of seborrheic keratosis (SK) has been a controversial subject in literature, with different molecular results. On the contrary, to the molecular approach, some have suggested that certain types of SK are indeed warts, due to their morphologic features. We decided to investigate the presence of coarse keratohyalin granules in cases of irritated SK. MATE...

Human skin biopsies were taken from patients with candidosis of the groin, axillary and submammary areas. The majority of the fungal cells were situated inside epithelial cells. The fungi invaded the entire stratum corneum. They were often found in parakeratotic epithelial cells. They could not be detected in noncornified cells of the malpighian layer. Mycelial forms predominated by far. They a...
