[Malignant eccrine poroma]

Area of Science:

• Dermatology
• Oncology
• Pathology

Background:

• Malignant eccrine poroma is a rare adnexal neoplasm.
• Early diagnosis and treatment are crucial for favorable outcomes.

Observation:

• An 82-year-old female presented with a back lesion.
• Clinical presentation suggested lymphangiosis carcinomatosa and axillary lymphadenopathy.
• Histopathological examination was performed.

Findings:

• The skin lesion was diagnosed as malignant eccrine poroma.
• The suspected lymphangiosis carcinomatosa and enlarged lymph node were confirmed to be inflammatory.
• This highlights the importance of thorough histopathological evaluation.

Implications:

• Differentiating inflammatory processes from metastatic disease is critical in oncology.
• Accurate diagnosis prevents unnecessary aggressive treatments.
• This case underscores the need for careful histopathological correlation in suspected adnexal tumors.
