The southernmost limit of the distribution of endemic Andean cutaneous leishmaniasis (CL), commonly known as Uta, is localized in the western Andean valleys of Ayacucho, Peru. This area is completely isolated from other regions endemic for this disease. Identification of the insect vector for Andean CL was carried out by combining entomologic and parasitologic approaches. Two Lutzomyia species ...

Cervical lymphadenopathy can be developed from various causes such as viral infection, bacterial infection, Kikuchi-Fujimoto disease, tuberculosis, malignancy, and reactive changes. In patients who have malignancy, metastatic lymphadenopathy is possible but it is rare that other concomitant diseases are in the same lymph node. We experienced a case of coexistence of Kikuchi necrotizing lymphade...

Kikuchi-Fujimoto disease was initially described as a self-limiting histiocytic necrotizing lymphadenitis in Japan in 1972, and is predominantly observed in women under the age of 30 year and in Asian populations. The pathogenesis is still poorly understood but is thought to include infections, and autoimmune and neoplastic diseases. The most common clinical manifestations are fever and painles...

Corynebacterium pseudotuberculosis or caseous lymphadenitis is a common condition in sheep and goats. Two cases are described involving otitis media-interna and, in one case, cerebellar abscessation. The first case began with otitis externa and progressed to cerebellar abscessation, presumably as a result of C. pseudotuberculosis infection based on the macroscopic appearance of the abscess. The...

Drug targeting enhances drug efficacy. This principle was tested in the treatment of an experimental visceral leishmaniasis. Using transmission electron microscopy (TEM) we localized pentamidine-loaded polymethocrylate nanoparticles in the liver of mice infected with Leishmania major and compared the ultrastructural changes in the parasites of these mice when they were treated with bound versus...

Lymphadenopathy can be caused by localized and systemic diseases. While viral and bacterial infections commonly cause lymphadenitis in young adults, tuberculosis (TB) is a common cause for lymphadenopathy in endemic areas. Besides, lymphadenopathy may be a presenting manifestation of malignancy, systemic disorders and some rare diseases. Thus, relevant evaluation and exclusion of commoner cause...

To the Editor: Dermatopathic lymphadenitis (DL) represents a rare benign lymphatic hyperplasia commonly associated with exfoliative or eczematoid dermatitis. DL was also reported to be a potential mimicker of lymphoma.[1] Here, we report the 18F‐fluorodeoxyglucose (18F‐FDG) positron emission tomography/ computer tomography (PET/CT) results and the histological findings of a 40‐year‐old female p...

A group of patients with Kawasaki disease (KD) initially present with cervical lymphadenitis or deep neck infection. These unusual KD presentations lead to unnecessary antibiotic therapy or surgical intervention, thereby delaying intravenous immunoglobulin treatment and increasing the risk of coronary artery damage. We present four KD patients whose initial presentations mimicked a retropharyng...
