Perforating disorders in patients with chronic renal failure (CRF), diabetes mellitus (DM), or both, may resemble any or all of the four classic cutaneous perforating disorders. However, due to the highly variable and overlapping histologic appearance of the lesions in patients with CRF, DM, or both, it may be useful to categorized these lesions as a distinct, yet encompassing process, termed b...

Elastosis perforans serpiginosa is a rare, primary perforating dermatosis, frequently associated with certain genetic diseases and characterized by the transepidermal extrusion of elastic fibers. The present case report describes this dermatosis in a 19-year old female patient with Down's syndrome, who presented with asymptomatic erythematous, keratotic papules in an arciform pattern, located o...

BACKGROUND Acanthosis nigricans is characterized by hyperpigmentation and hyperkeratosis of the skin or mucous membranes. Its malignant form is associated with internal neoplasms, especially gastric adenocarcinoma (55-61%). Coexistence with prostate cancer is uncommon. In the paraneoplastic type of this dermatosis, the skin and mucous lesions are characteristically of more sudden onset and more...

LABD: Linear IgA bullous dermatosis INTRODUCTION Linear IgA bullous dermatosis (LABD) is a rare disorder characterized by tense bullae arranged annularly on the trunk and extremities. LABD is usually idiopathic or associated with medications, classically vancomycin and nonsteroidal anti-inflammatory drugs. Rarely, LABD has been reported in association with lymphoproliferative disorders, sarcoma...

Neutrophilic dermatosis of the dorsal hands is a recently described disorder. It is still debatable if it constitutes a separate entity, a variant of Sweet syndrome or pyoderma gangrenosum or an overlap disorder of both. We report the clinical features, histopathological findings, and evolution of a 35-year-old patient with the diagnosis of neutrophilic dermatosis of the dorsal hands and distan...

Sweet's syndrome (SS), or acute febrile neutrophilic dermatosis, is marked by fever, leukocytosis, and painful erythematous papules/plaques resulting from neutrophil migration and accumulation in the dermis. This condition has been associated with underlying hematologic as well as solid malignancies. We describe a unique case of SS in a patient with metastatic papillary follicular thyroid carci...

Neutrophilic dermatosis of the dorsal hands is a variant of Sweet's syndrome. We herein describe an 83-year-old woman with a neutrophilic dermatosis of the dorsal hands associated with a "myeloproliferative neoplasm, unclassifiable" and a simultaneous cancer of colon. To our knowledge, and after a search in PubMed, the association of Sweet's syndrome with a "myeloproliferative neoplasm, unclass...

Subcorneal pustular dermatosis is a disease that has coalescent, flaccid, recurrent pustules. We do not know everything about its etiology or pathogenesis; however, its autoimmune mechanism links it with neoplastic or immunologic diseases. First line treatment is dapsone. We describe the case of a classic subcorneal pustular dermatosis in a patient in who we could not use dapsone (sulpha drugs ...
