Leishmaniasis mucosa nasolaringotraqueal en un adolescente / Nasolaryngotracheal mucosal leishmaniasis in an adolescent

La leishmaniasis es un problema creciente de salud pública, que produce un gran impacto social. La leishmaniasis laríngea y sin puerta de entrada evidente es rara, en especial en pacientes inmunocompetentes. Describimos un caso de leishmaniasis laríngea con extensión traqueal y estenosis secundaria en un adolescente previamente sano y sin factores de riesgo ambiental o personal.

Leishmaniasis is a growing public health problem and it produces a great social impact. Laryngeal leishmaniasis without obvious gateway is rare; especially in immunocompetent patients. We report a case of laryngeal leishmaniasis with tracheal involvement and stenosis on a previously healthy teenager without environmental or personal risk factors.

Old world leishmaniasis presenting as a nasal mass.

Mucosal leishmaniasis is a major problem in Latin America but has been rarely noticed in our region. Although there have been a few reports of mucosal involvement especially in the oral cavity from Southwest Iran, yet none have been presented from the Northeast where Leishmania tropica is the major concern. We report a patient with endonasal leishmaniasis due to L. tropica, an extremely rare entity in immunocompetent patients in our region. He presented with a mass in the left nasal vestibule causing a sense of obstruction on the same side, accompanied by occasional rhinorrhea and mild epistaxis. This case exemplifi es the need for considering leishmaniasis as a differential diagnosis for nasal obstruction in this endemic area.

A case of nasal myiasis due to Oestrus ovis (Diptera: Oestridae) in a llama (Lama glama) / Um caso de miíase nasal devido a Oestrus ovis (Diptera: Oestridae) em lhama (Lama glama)

Infection by the larval form of Oestrus ovis (sheep bot fly) is common in many areas of Peru. This is an obligate parasite of sheep and goats, and it is the cause of oestrosis, or nasal myiasis, which can lead to severe clinical manifestations in livestock. A case of myiasis caused by O. ovis in a llama (Lama glama) in Cuzco, Peru, is reported here. This llama presented with respiratory distress and died due to bilateral hemorrhagic pneumonia. During the necropsy, six intact dipterous larvae were recovered from the nasal fossae and cranial sinuses being identified as O. ovis. This is the first report of nasal myiasis in llamas due to O. ovis in Peru.

Infecção pela forma larval de Oestrus ovis (bicho da cabeça) é comum em muitas regiões do Peru. Este é um parasito obrigatório de ovinos e caprinos, e é a causa de oestrose ou miíase nasal, que pode conduzir à manifestações clínicas graves nos animais. Relatou-se um caso de miíase causada por O. ovis numa lhama (Lama glama) em Cuzco, Peru. A lhama apresentou insuficiência respiratória e morreu de pneumonia bilateral hemorrágica. Durante a necropsia, seis larvas intactas do díptero foram recuperadas das fossas nasais e dos seios cranianos e identificadas como O. ovis. Este é o primeiro relato de miíase nasal em lhamas por O. ovis no Peru.

Polymorphic ecthymatoid dermosporidiosis.

We report the case of a young Chhattisgarhi male with polymorphic dermosporidiosis (cutaneous rhinosporidiosis). He had multiple subcutaneous nodules and an ecthymatoid skin lesion along with nasal rhinosporidiosis. The diagnosis was confirmed by demonstration of sporangia with endospores in fine-needle aspiration cytology (FNAC), histopathology, and imprint smear from the skin lesions. Treatment was by surgical excision, electrocoagulation, and dapsone. There was no recurrence. Dermatologists should be aware of the diverse cutaneous manifestations of this primarily nasal disease. This is the second published report of polymorphic dermosporidiosis, and the first one reporting an ecthymatoid lesion.

Oestrus ovis [sheep nasal fly] infesting the eyes and the nose of a camel keeper family

Myiasis is a medical and veterinary health problem in many animal rearing countries. It is not a new problem in Egypt. A family of 5 persons was infested in the eyes [5] and nose [2] with the larvae of Oestrus ovis. It was concluded that the physicians in the MOH rural health units should keep in mind ophthalmomyiasis when dealing with non-specific catarrhal conjunctivitis, particularly those people who are concerned with rearing of farm animals
