RESUMO
Leishmaniasis is a protozoal infection transmitted by a sandfly vector. In Germany, leishmaniasis of the mucous membranes is a rare condition and usually due to extension of local skin disease into the mucosal tissue via direct extension, bloodstream or lymphatics. We report a case of endonasal leishmaniasis in a female German resident who presented in a university hospital with nasal obstruction. Histology of the left nasal septum biopsy was suggestive of leishmaniasis. The molecular detection of DNA was positive for leishmania infantum. The patient was successfully treated as a case of mucocutaneous leishmaniasis receiving liposomal amphotericin follow up visits showed significant improvement with no recurrence.

OBJECTIVE: To explore a method for removing a living leech from the nasal cavity. MATERIALS AND METHODS: A total of 5 patients with nasal leech were examined. Nasal endoscopy revealed the presence of a wriggling leech in the nasal cavities of each of these patients. A negative suction tube with an inner diameter of 3 mm and a negative pressure of 30-40 kp was used to remove these leeches. In each case, this suction tube was aimed at the free end of the leech, and the leech was gradually and slowly sucked into the tube. The suckers of the removed leeches were examined to ensure that no leech fragments remained within each patient. RESULTS: In all 5 cases, the intact leech was successfully removed. No surgical complications occurred. CONCLUSIONS: The negative suction method can successfully remove nasal leeches.

Rhinosporidiosis is a chronic granulomatous disease that primarily affects the mucous membranes of the nose and nasopharynx. It is caused by Rhinosporidium seeberi. Clinically it presents as a reddish, bleeding, polypoid mass with a characteristic strawberry-like appearance on its surface, which is caused by the presence of mature sporangia. In the case described here, a 35-year-old man presented with a 6-month history of a slowly growing polypoid mass in his left nasal cavity. The surface of the mass was smooth, pale, and covered with nasal mucosa. It was attached to the nasal septum. Fine-needle aspiration cytology was suggestive of a parasitic cyst. The mass was excised with the use of local anesthesia. Histopathologic examination of the resected specimen revealed rhinosporidiosis. Prior to this diagnosis, the patient had not exhibited most of the typical clinical features that are suggestive of rhinosporidiosis. In the case of a nasal mass, a diagnosis of rhinosporidiosis is important to establish prior to any surgery because bleeding during and after surgery is usually profuse and can be life-threatening. The site of the excised mass should be cauterized to prevent recurrence.

OBJECTIVE: We report a case of an Oestrus ovis larva which developed into the second larval stage within a healthy, immunocompetent human, and we review the relevant literature. METHODS: Clinical case report and Pubmed search of reports of human nasal myiasis due to Oestrus ovis, especially those describing the larval stage. RESULTS: Humans are not normally hosts of the sheep nasal bot fly, but infestations by its larvae have been described. The eye is the most common site, but larvae have occasionally been found in the human nose. Transformation of larvae into the second and third stages, within the human nose, is even more uncommon. CONCLUSION: To the best of our knowledge, we report the first Swedish case, and the third case world-wide, of Oestrus ovis larval development beyond the first larval stage, within an immunocompetent, healthy human.

INTRODUCTION: The leech is an aquatic worm living in fresh water, especially in tropical areas. It may be found exceptionally in the upper aerodigestive tract (UADT) after consumption of spring water or water from natural wells, after swimming in still waters (lakes and dams). The author's objective was to study epidemiological, clinical, therapeutic, and evolutive aspects of this infestation. PATIENT AND METHODS: This prospective 2-year study was carried out from January 1, 2007 to December 31, 2008. We included all patients consulting at the emergency unit presenting with leeches in the UADT. RESULTS: Twenty patients living in rural settings were included: 16 children, mostly boys (sex ratio 3:1). All cases were recorded during the summer season, with 14 cases due to consumption of fresh water and six due to swimming in still waters. The delay between infestation and onset of symptoms ranged from 2 to 15 days. Leeches were found in the oropharynx (six cases), the nasopharynx (five cases), the hypopharynx (six cases), and the glottis (three cases). An anemia syndrome was noted in four patients. All parasites were removed. All patients were given local antiseptics and analgesics. Patients with anemia were given iron supplementation. The outcome was favorable for all patients. DISCUSSION: UADT leeches are not uncommon in Morocco. The infestation is usually observed in the summer. Symptoms vary according to UADT localization. The diagnosis should be made rapidly to prevent complications. Whatever the localization, removing the parasite is difficult. In laryngeal localizations induction general anesthesia is recommended, without intubation. Evolution after treatment is rapidly favorable, with complete disappearance of symptoms.

We present a case of a 44-year-old man with complaints of double-sided nasal obstruction and a foreign body sensation. A polypoid lesion was seen in the nasopharynx and was later completely excised. Histologic examination showed a respiratory epithelial adenomatoid hamartoma. The clinical and pathological features of this rare tumor as a cause of nasal obstruction are discussed.

Leishmania is currently one of the most clinically important protozoa in otorhinolaryngology. Mediterranean countries, including Spain, have endemic HIV and L. infantum. Dogs are the most important Leishmania reservoir. Leishmaniasis is transmitted basically by the bite of infected female Phlebotomus sandflies. Its clinical development depends mainly on the host's cellular immunity (TCD4+ lymphocyte count). About 400 cases of HIV-visceral leishmaniasis have been reported in Spain. However, exclusively cutaneous presentation of HIV-leishmaniasis coinfection has been observed in only 2-3% of cases. We report the case of a female HIV+ patient who developed cutaneous leishmaniasis of the nasal vestibule by L. infantum. The patient was treated satisfactorily with a combination of parenteral Pentostam (sodium stilbogluconate) and periodic intralesional injections of Pentostam. The patient was included in a secondary prophylaxis protocol for visceral leishmaniasis with a monthly dose of Glucantime (meglumine antimoniate) for life.
