Differential Diagnosis for Post-Vasectomy Incision Site Lesion
Single Most Likely Diagnosis
- Hematoma: A small blood blister-like area at the incision site is consistent with a hematoma, which is a common complication after vasectomy. The absence of swelling or bruising suggests a small, localized hematoma.
Other Likely Diagnoses
- Suture granuloma: A small, cherry-like lesion at the incision site could be a suture granuloma, which is an inflammatory reaction to the suture material.
- Wound infection: Although there is no swelling or bruising, a small, localized infection could present with a blood blister-like lesion.
- Vasculitis: Inflammation of the blood vessels at the incision site could cause a small, cherry-like lesion.
Do Not Miss Diagnoses
- Abscess: A small, localized abscess could present with a blood blister-like lesion and may not have significant swelling or bruising. Missing this diagnosis could lead to serious infection and complications.
- Necrotizing fasciitis: Although rare, necrotizing fasciitis is a life-threatening condition that could present with a small, localized lesion at the incision site.
Rare Diagnoses
- Pyogenic granuloma: A rare, benign vascular tumor that could present as a small, cherry-like lesion at the incision site.
- Kaposi's sarcoma: A rare, malignant vascular tumor that could present as a small, cherry-like lesion, although this is highly unlikely in this context.
- Angiosarcoma: A rare, malignant vascular tumor that could present as a small, cherry-like lesion, although this is highly unlikely in this context.
