[Non-Hodgkin's lymphoma and pustular psoriasis: a case report]
Abstract:
Psoriasis has been hypothesized to be associated with lymphoma. Several studies demonstrated an epidemiological relationship between these two entities. Patients with psoriasis are at increased risk for developing lymphoproliferative malignancies. This risk can be also the consequence of immunosuppressive therapies (methotrexate or cyclosporine). We report a 65-year-old man who presented with diffuse erythematous plaques with pustular or squamous borders. Histopathologic evaluation concluded to a pustular psoriasis. We discover simultaneously a stage 4 bone marrow B lymphoma of low grade of malignancy. This case report highlights the relationships between psoriasis and lymphoma.

Chickenpox
Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...
Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
