Cutaneous leishmaniasis is a significant global health issue that often affects travelers returning from endemic regions. Recently, medical professionals identified the first imported case of New World cutaneous leishmaniasis in Romania. A 25-year-old woman developed progressive skin lesions after visiting Panama and Costa Rica. Because Romania is a non-endemic country, the diagnosis initially proved difficult.
Initially, a standard skin biopsy showed only nonspecific inflammation. Consequently, the medical team performed a second biopsy. This deeper investigation successfully identified amastigotes within the patient's macrophages. To confirm the specific species, specialists used advanced molecular tools. Both ITS1 sequencing and hsp70 phylogenetic analysis verified the presence of Leishmania panamensis.
Clinicians chose oral miltefosine as the primary treatment for this patient. She followed a 28-day regimen, which led to a gradual but steady improvement of her skin lesions. Ultimately, the ulcers healed completely, leaving only minor atrophic scars. Most importantly, follow-up evaluations after 473 days showed no signs of disease relapse.
This case emphasizes why doctors in non-endemic regions must stay alert. Early recognition of New World cutaneous leishmaniasis prevents the progression to more severe mucocutaneous forms. Therefore, healthcare systems should prioritize access to molecular diagnostic tools for travelers with suspicious skin lesions.
Symptoms typically include progressive, painless skin ulcers that develop weeks or months after a sandfly bite. These lesions often appear on exposed areas like the arms or face.
Miltefosine is an oral medication usually taken for 28 days. It is highly effective against specific species like L. panamensis and offers a convenient alternative to injectable treatments.
Molecular tests such as PCR and hsp70 sequencing are essential for species identification. Different Leishmania species require different management strategies and carry varying risks of complications.

An 11-year Swedish registry study of 618 uterine sarcoma patients found that minimally invasive surgery yielded survival comparable to open surgery in early stages. However, adjuvant chemotherapy conferred no survival benefit in localized or advanced disease, highlighting stage and histology as key outcomes.
