Summary

This summary is machine-generated.

Encapsulated papillary carcinoma (EPC) is typically indolent. This case highlights that even advanced-stage male EPC with skin ulceration and lymph node involvement can exhibit an indolent course.

Area Of Science

  • Oncology
  • Pathology
  • Urology

Background

  • Encapsulated papillary carcinoma (EPC) is a rare invasive breast carcinoma.
  • EPC typically presents with an indolent course and excellent prognosis.
  • Data on EPC in males is limited due to its rarity.

Purpose Of The Study

  • To report a rare case of pure encapsulated papillary carcinoma in a male patient.
  • To analyze the clinical presentation, management, and outcome of advanced-stage EPC in a male.
  • To underscore the indolent nature of EPC, irrespective of advanced stage.

Main Methods

  • Case report presentation.
  • Review of clinical data and pathological findings.
  • Staging and outcome assessment.

Main Results

  • A male patient presented with pure EPC, skin ulceration, and lymph node metastasis (ypT4bN1a).
  • Despite advanced stage, the tumor demonstrated an indolent behavior.
  • The case highlights the importance of recognizing the inherent indolent nature of EPC.

Conclusions

  • Encapsulated papillary carcinoma, even in advanced stages and in males, can follow an indolent course.
  • Accurate staging and understanding the tumor's behavior are crucial for appropriate management.
  • Further research is needed to fully elucidate EPC characteristics in the male population.
