Imaging analysis of superficial soft tissue lymphomas

Abstract

Purpose: To describe imaging findings in superficial soft tissue lymphomas, especially those located in the skin and subcutaneous layer.

Materials and methods: This study included 44 pathologically confirmed superficial lymphoma lesions. Imaging analysis included the size, margin, location, morphology, homogeneity and multiplicity.

Results: A nodular form was the most common (21/44, 47.7%) morphology, and of them, 18 demonstrated a streaky appearance. Most of the lesions demonstrated ill-defined margins (26/44, 59.1%) and homogeneous patterns (35/44, 79.5%).

Conclusions: The imaging findings of superficial soft tissue lymphomas were non-specific. However, if images show multiple nodular lesions with ill-defined margins, we should consider this diagnosis.
