Abstract Background Oral lichen planus (OLP) is a chronic inflammatory oral mucosa disease that recognized as an potentially malignant disorder. However, the nature of OLP remains unclear. Methods We designed this study to examine demographic and clinical characteristics patients with evaluate associated transformation rate. A total 565 histopathological diagnosis who presented at our departmen...

BACKGROUND Benign lichenoid keratosis (BLK, LPLK) is often misdiagnosed clinically as superficial basal-cell carcinoma (BCC), especially when occurring on the trunk. However, BCCs undergoing regression may be associated with a lichenoid interface dermatitis that may be misinterpreted as BLK in histopathologic sections. METHODS In order to assess the frequency of remnants of BCC in lesions int...

The aims of the study weres to determine the clinical & histopathological correlation of papulosquamous disorders and to know various tissue reaction patterns of papulosquamous disorders. A total 179 patients with clinical features of papulosquamous disorders were included in this study. Biopsy was taken and sent for haematoxylin and eosin stain and examination. Finally clinico-histopathologica...

BACKGROUND Nail apparatus melanoma is known to be associated with a poor prognosis, mainly because of a delay in diagnosis that is made at an invasive stage. This delay is particularly true in cases involving amelanotic melanoma. To our knowledge, only 1 case of in situ amelanotic melanoma of the nail unit has previously been described. We report 3 cases of in situ amelanotic melanoma with clin...

BACKGROUND The occurrence of lichenoid keratosis (LK) on the face is not well characterized, and the histopathologic distinction between LK and lupus erythematosus (LE) occurring on the face is often indeterminate. The authors aimed to describe differences between LE and LK occurring on the face by hematoxylin and eosin alone. METHODS Cases of LK and LE were obtained using computer-driven que...

INTRODUCTION Vandetanib (ZD6474, Zactima) is a novel inhibitor of multiple tyrosine kinases that has been used for the treatment of various malignancies including medullary thyroid carcinoma. The drug functions primarily via inhibitory effects on vascular endothelial growth factor receptors, epidermal growth factor receptors, and the RET-tyrosine kinase system. As with other targeted chemothera...

Lichenoid and granulomatous dermatitis is a new entity which is histologically defined by a band like lymphocytic infiltration in the upper portion of the dermis with obscuring the dermoepidermal junction and accompanied by basal layer degeneration and granulomatous inflammation. Herein, we presented two Iranian women with similar cutaneous and histopathologic findings. Both patients had asympt...

OBJECTIVE We aimed to evaluate the clinical features of sclerodermatous chronic graft-versus-host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (AHSCT). METHODS We retrospectively analyzed 423 patients who underwent AHSCT. We assessed age, sex, pre-transplant diagnosis, conditioning regimen, GVHD prophylaxis, and occurrence of acute GVHD (aGVHD), chronic lichenoid an...
