Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Background:

Primary cutaneous plasmacytoma is a rare neoplastic proliferation of plasma cells confined to the skin.
It is diagnosed in the absence of systemic or bone marrow involvement.
Multiple cutaneous plasmacytomas are exceptionally rare and associated with a poorer prognosis than solitary lesions.

Observation:

This report details an 87-year-old female patient diagnosed with multiple primary cutaneous plasmacytomas.
The case highlights the clinical presentation, histopathological findings, and immunohistochemical profile.
The patient's disease evolution and management are also discussed.

Findings:

The patient presented with multiple distinct skin lesions characteristic of plasmacytoma.

Histopathological and immunohistochemical analyses confirmed the monoclonal plasma cell origin.

The case underscores the diagnostic challenges and rarity of multiple cutaneous plasmacytomas.

Implications:

This case contributes to the limited literature on multiple primary cutaneous plasmacytomas.
Understanding the clinical and pathological spectrum is crucial for accurate diagnosis and management.
Further research into the pathogenesis and optimal treatment strategies for this rare entity is warranted.
