Acral persistent papular mucinosis: is it an under-diagnosed disease?

Area of Science:

• Dermatology
• Pathology

Background:

• Acral persistent papular mucinosis is a rare subtype of localized lichen myxedematosus.
• This condition is characterized by persistent papules primarily affecting the extremities.

Observation:

• The case involves a female patient presenting with clinical signs consistent with acral persistent papular mucinosis.
• Histopathological examination confirmed the diagnosis.

Findings:

• The patient exhibited acrally located papules.
• The clinical course was benign yet persistent, aligning with disease characteristics.
• Both clinical and histopathological criteria were met, confirming the diagnosis.

Implications:

• This case contributes to the limited literature on acral persistent papular mucinosis.
• Highlights the importance of clinical and histopathological correlation for diagnosing rare dermatoses.
• Enhances understanding of localized lichen myxedematosus variants.
