Solitary Peutz–Jeghers type hamartoma in a Nigerian: A case report of a rare finding and review of literature.
Background: We report a case of solitary Peutz–Jeghers (P‑J) type hamartomatous polyp in the sigmoid colon of an asymptomatic Nigerian without other diagnostic criteria for full‑blown P‑J syndrome. Case Report: During colonoscopy for a 58‑year‑old man, a solitary, pedunculated polyp was seen in the sigmoid colon. Histopathological examination of the endoscopically resected mass revealed the classical features of P‑J type hamartoma. A search for lentigines on the skin or mucous buccal membranes was negative. There is no family history of such findings. Conclusion: The case here presented is truly rare as a review of the scientific literature appears, to the best of our knowledge, not to contain such a unique presentation from our locality nor indeed from among Black Africans. We conducted a review of the literature and wished to highlight the evolving concept that solitary P‑J polyps be considered a distinct disease entity when it appears in the absence of other features of the syndrome complex
