Rare Location of Dracunculus Medinensis Infection
Indian Journal of Dermatology, Venereology and Leprology
|February 3, 2017
Summary
Vulvar infection with Dracunculus medinensis, a rare parasitic disease, was misdiagnosed as a tumor. Diagnosis was confirmed through histopathology revealing the parasite within fibrous tissue.
Area of Science:
- Parasitology
- Dermatology
- Pathology
Background:
- Dracunculus medinensis (Guinea worm) infection typically affects subcutaneous tissues and lower limbs.
- Vulvar involvement by Dracunculus medinensis is exceptionally rare, often leading to misdiagnosis.
Observation:
- A case presented with a vulvar swelling clinically resembling a neoplastic growth.
- The swelling was characterized as an oval, firm, and mobile mass on the left labia majora.
Findings:
- Gross examination revealed a coiled, thread-like adult parasite within the excised growth.
- Histopathology confirmed the presence of parasite sections embedded in a fibrocollagenous stroma with inflammatory cell infiltration (lymphocytes, plasma cells, eosinophils).
Implications:
- This case highlights the importance of considering rare parasitic infections in gynecological differential diagnoses.
- Accurate diagnosis of Dracunculus medinensis is crucial for appropriate management and public health awareness regarding this neglected tropical disease.

01:30Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
01:22American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
01:12Giardiasis
Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
