This case highlights trichodiscomas, benign skin tumors, and their association with colon polyps. Patients with these pilosebaceous hamartomas should be screened for gastrointestinal polyposis.

Area of Science:

  • Dermatology
  • Gastroenterology
  • Oncology

Background:

  • Trichodiscoma is an uncommon benign tumor originating from the pilosebaceous unit.
  • Pilosebaceous tumors, including trichodiscomas, fibrofolliculomas, and perifollicular fibromas, can occur concurrently.
  • Birt-Hogg-Dubé syndrome is a known condition linking trichodiscomas with familial colonic polyposis.

Observation:

  • An 83-year-old male presented with multiple asymptomatic papulonodular skin lesions.
  • The patient had a history of colonic adenomatous polyps and a family history of colon cancer.
  • Skin biopsies confirmed the presence of trichodiscomas.

Findings:

  • The case presents a rare co-occurrence of trichodiscomas and a history of colonic polyposis.
  • This presentation suggests a potential link between pilosebaceous hamartomas and gastrointestinal polyposis.

  • The combination of trichodiscomas and colonic polyposis has been previously reported primarily in the context of Birt-Hogg-Dubé syndrome.

    • Implications:

    • Patients diagnosed with hamartomas of the pilosebaceous system warrant investigation for digestive tract polyposis.
    • Early screening for gastrointestinal polyposis in individuals with trichodiscomas may improve patient outcomes.
    • This case underscores the importance of considering systemic associations in dermatological diagnoses.
