This study details a rare case of multiple cylindromas arranged linearly on a patient's lower extremity. The extensive tumor count, sparing the scalp, and overlapping features with eccrine spiradenoma are notable findings.

Area of Science:

  • Dermatology
  • Oncology
  • Pathology

Background:

  • Multiple cylindromas are rare benign adnexal neoplasms.
  • Linear arrangement of cylindromas is an exceptionally uncommon presentation.
  • Distinguishing cylindromas from similar adnexal tumors like eccrine spiradenoma can be challenging.

Observation:

  • A patient presented with over 100 cylindromas predominantly on the lower right extremity.
  • The scalp, a common site for cylindromas, was notably spared in this case.
  • Histopathological examination revealed some tumors with features overlapping with eccrine spiradenoma.

Findings:

  • This case represents the first documented instance of multiple cylindromas exhibiting a distinct linear arrangement.
  • The extensive cutaneous involvement without scalp manifestation is a unique characteristic.

  • The observed overlapping histopathological features highlight diagnostic complexities.

    • Implications:

    • This report expands the known clinical spectrum of cylindromas.
    • Understanding linear presentations may aid in earlier diagnosis and management.
    • Further research into the pathogenesis of linear and overlapping adnexal neoplasms is warranted.
