Abstract

Southeastern Anatolia and the Mediterranean regions of Turkey are known as endemic areas for cutaneous leishmaniasis (CL). In this report, a 64 years-old male patient with CL caused by Leishmania infantum has been presented. The patient who was inhabiting in Ankara (Central Anatolia region, Turkey) complained from a lesion on his right ring finger for the last six months. He has a cat and has been engaged with gardening. Overall, he was healthy with the exception of hypertension and glucose intolerance. The patient had not left Ankara since the last seven months, however, he had previously been to the Aegean coast during his summer holiday. The examination of the 4th phalanx of his right hand revealed the presence of a 3 x 3 cm erythematous, slightly swollen lesion, at the center of which 1.5 x 1.5 cm ulcerative area covered with a hemorrhagic crust, was detected. Neither axillary or cervical lymphadenopathy, nor hepatosplenomegaly could be observed. The routine examinations, including complete blood count, serum biochemistry, chest X-ray and abdominal ultrasonography were within normal limits. Giemsa stained smears prepared from aspiration of the lesion revealed amastigote-like organisms and leishmania promastigotes were grown in NNN media. PCR amplification of the specimen indicated the presence of a positive DNA band of 420 bp specific for Leishmania spp. The serum sample of the patient revealed positivity for leishmaniasis by the rapid rK39 test and immunofluorescence antibody (IFAT) test. The organism was identified as L.infantum by PCR-RFLP applied to the cultivated organism. The examination of his cat’s serum for leishmaniasis by IFAT and PCR, were negative. The exact way of transmission had not been confirmed for the patient. However, when long incubation period of CL was considered, the transmission might probably occurred during his summer stay in the Aegean coast. This case was presented to withdraw attention to a delayed diagnosis of CL which developed in a non-endemic area and which was due to L.infantum instead of the more common L.tropica species.

Özet

Türkiye’de özellikle Güneydoğu Anadolu ve Akdeniz bölgeleri kütanöz leyşmanyazis (KL) için endemik bölgeler olarak bilinmektedir. Bu raporda, Ankara’da yaşayan 64 yaşındaki erkek hastada gelişen Leishmania infantum’a bağlı bir KL olgusu sunulmaktadır. Hasta altı aydır sağ el yüzük parmağı üzerindeki iyileşmeyen yara nedeniyle kliniğimize başvurmuştur. Kedi besleyen ve bahçe işleriyle uğraşan olgunun hipertansiyon ve glukoz intoleransı dışında başka bir hastalığı bulunmadığı; lezyon oluşmadan önceki son yedi aylık dönemde şehir dışına çıkmadığı, ancak daha önce Ege Bölgesinde tatil amaçlı bulunduğu öğrenilmiştir. Dermatolojik muayenesinde, sağ elin dördüncü falanks üzerinde 3 x 3 cm boyutunda, deriden kabarık, eritematöz lezyon ve ortasında 1.5 x 1.5 cm boyutunda üzeri hemorajik kurutla kaplı ülsere lezyon gözlenmiştir. Yapılan sistemik muayenesinde, aksiler ve servikal lenfadenopati ve hepatosplenomegali saptanmamıştır. Hastanın tam kan, rutin biyokimya, akciğer grafisi ve tüm batın ultrasonografisi normal sınırlardadır. Olguda leyşmanyazis tanısı; yara dokusu aspirasyon materyalinden hazırlanan yaymada Giemsa boyama ile amastigot benzeri yapıların görülmesi; NNN besiyerinde Leishmania promastigotlarının üremesi ve PCR yöntemiyle Leishmania spp. için özgül 420 baz çiftlik bölgede pozitif bant görülmesiyle konulmuştur. Ayrıca hastanın serum örneğinde rK39 hızlı tanı testi ve immünofloresan antikor (IFAT) testiyle de leyşmanyazis açısından pozitif sonuç alınmıştır. Olgunun kültür örneğine uygulanan PCR-RFLP yöntemi sonucu, etken L.infantum olarak tanımlanmıştır. Hastanın evcil kedisinden alınan serum örneğinde ise IFAT ve PCR ile leyşmanyazis etkeni saptanamamıştır. Olgumuzda bulaş yolu tam olarak netleştirilememiş, ancak KL’de kuluçka döneminin uzun olduğu göz önüne alındığında, hastamızın bu paraziti Ege Bölgesindeki tatili sırasında almış olabileceği düşünülmüştür. Bu olgunun, ülkemizin endemik olmayan bölgesinde görülmesi ve KL’nin en sık etkeni olan L.tropica yerine etken olarak L.infantum’un saptanmış olması nedeniyle sunulması uygun bulunmuştur.
