**Core Concept**
Rhinosporidiosis is a chronic granulomatous infection caused by Rhinosporidium seeberi, characterized by the formation of polyps in the nasal mucosa and other tissues. The ideal treatment involves a combination of surgical excision and antifungal therapy to prevent recurrence.

**Why the Correct Answer is Right**
The correct treatment for rhinosporidiosis involves surgical excision of the polyp to prevent further growth and antifungal therapy with intravenous pentamidine to reduce the recurrence rate. This approach is based on the understanding that Rhinosporidium seeberi is a protozoan parasite that requires a combination of mechanical removal and antifungal treatment to achieve complete resolution. The use of pentamidine is thought to inhibit the growth of the parasite and prevent recurrence.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not specify the use of antifungal therapy, which is essential in the treatment of rhinosporidiosis.
**Option B:** This option is incorrect as it only mentions surgical excision, which is not sufficient to prevent recurrence.
**Option C:** This option is incorrect as it mentions the use of antibiotics, which are not effective against Rhinosporidium seeberi.

**Clinical Pearl / High-Yield Fact**
Rhinosporidiosis is a rare but chronic condition that requires a combination of surgical excision and antifungal therapy to achieve complete resolution. The use of pentamidine is a key component of the treatment regimen.

**Correct Answer: D. Surgical excision along with intravenous pentamidine.**
