Cutaneous lymphocytomas: clinical and histological aspects

Area of Science:

• Dermatology
• Pathology
• Oncology

Background:

• Cutaneous lymphocytomas present diagnostic challenges.
• Distinguishing benign lymphocytoma from lymphocytic infiltration of the skin (Jessner) is crucial.

Purpose of the Study:

• To review cases of cutaneous lymphocytoma.
• To assess diagnostic agreement between clinical and histological findings.
• To evaluate treatment outcomes and relapse rates.

Main Methods:

• Retrospective review of 25 cutaneous lymphocytoma cases.
• Comparison of clinical diagnoses with histological findings.
• Analysis of treatment responses and follow-up data.

Main Results:

• Diagnostic discrepancies were noted between clinical and histological assessments, particularly for Jessner's lymphocytic infiltration.
• Treatment resulted in complete remission for 8 patients and partial remission for 5.
• Relapses occurred in 8 patients despite initial remission.
• No systemic lymphoreticular malignancies were observed.

Conclusions:

• There is notable uncertainty in the histological diagnosis of cutaneous lymphocytomas.
• Further examination is essential for suspicious skin lesions to rule out systemic disease.
• Accurate differentiation between benign lymphocytoma and Jessner's lymphocytic infiltration is critical for appropriate patient management.
