A patient presented with subcutaneous nodules over the Iliac Crest, snow flake oplacity in eye. Skin Scraping contains microfilaria and adult worms of
**Core Concept**
The patient's presentation of subcutaneous nodules over the Iliac Crest and snowflake opacity in the eye is indicative of a parasitic infection, specifically Loa loa filariasis, also known as African eye worm. This condition is caused by the Loa loa parasite, which is transmitted through the bite of an infected deer fly.
**Why the Correct Answer is Right**
The Loa loa parasite has a unique lifecycle, where it migrates through the bloodstream and can be seen in the eye, causing the characteristic snowflake opacity. The subcutaneous nodules are a result of the adult worms residing in the skin. The skin scraping containing microfilaria and adult worms is a diagnostic finding for Loa loa filariasis.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because the Loa loa parasite is not typically associated with the presence of microfilaria in the skin scraping.
* **Option B:** This option is incorrect because the skin scraping would not contain microfilaria of Wuchereria bancrofti, which is a different species of filarial parasite.
* **Option C:** This option is incorrect because the Loa loa parasite is not typically associated with the presence of adult worms and microfilaria in the skin scraping.
**Clinical Pearl / High-Yield Fact**
Loa loa filariasis is often referred to as the "African eye worm" due to the characteristic migration of the parasite through the eye, causing snowflake opacity. This condition is relatively rare and typically seen in travelers to endemic areas.
**Correct Answer: D. Loa loa**
