A 67-year-old woman presented with a 3-month history of patchy alopecia areata (AA)-like hair loss and multiple painful enlarged lymph nodes at cervical, nuchal, and left axillary site. The patient was on follow-up for IgM monoclonal gammopathy of undetermined significance, stable for many years. A punch biopsy from a patch of the temporal scalp revealed the presence of B-cell lymphoid infiltrates consistent with marginal zone B-cell lymphoma (MZL). Other staging examinations were conducted to make a definitive diagnosis of nodal MZL with secondary cutaneous involvement. The patient showed a complete remission of the alopecia, without evidence of scarring, after immunochemotherapy for lymphoma.
