Melanosis Coli: A Case of Mistaken Identity-A Case Report.

INTRODUCTION: Melanosis coli is a condition in which the colon develops a brown to black discoloration. It is associated with chronic laxative use and frequently diagnosed incidentally during colonoscopy or histopathologic evaluation. CASE PRESENTATION: A 74-year-old woman presented to the Emergency Department with severe abdominal pain and bilious emesis. During a cecal volvulus repair, her melanosis coli was nearly misdiagnosed as bowel ischemia. DISCUSSION: Melanosis coli is a diagnostic finding that can easily be confused with bowel ischemia, which may create a dilemma for the surgeon who is attempting to make a decision regarding the extent of a colonic resection. As such, a pathology consult is warranted in any patient with suspected ischemic colitis and concerns for concomitant melanosis coli.

A unique case of popliteal artery transection after a motorcycle collision.

Popliteal artery injuries may have devastating consequences if not recognized in a timely fashion. The risk of delayed diagnosis of a vascular injury is particularly high in blunt trauma to the lower extremity. We present a case of popliteal artery injury that is unusual in two respects: severity (a complete transection in the setting of a blunt injury) and lack of clinical and radiographic signs of the commonly associated musculoskeletal injuries.

Congenital Renal Fusion and Ectopia in the Trauma Patient.

We present two separate cases of young male patients with congenital kidney anomalies (horseshoe and crossed fused renal ectopia) identified following blunt abdominal trauma. Despite being rare, ectopic and fusion anomalies of the kidneys are occasionally noted in a trauma patient during imaging or upon exploration of the abdomen. Incidental renal findings may influence the management of traumatic injuries to preserve and protect the patient's renal function. Renal anomalies may be asymptomatic or present with hematuria, flank or abdominal pain, hypotension, or shock, even following minor blunt trauma or low velocity impact. It is important for the trauma clinician to recognize that this group of congenital anomalies may contribute to unusual symptoms such as gross hematuria after minor trauma, are readily identifiable during CT imaging, and may affect operative management. These patients should be informed of their anatomical findings and encouraged to return for long-term follow-up.
