Our patient is a 32-year-old woman of Cape Verdean descent, who initially presented in February of 2010 with 1-month course of non-productive cough. She also stated that she had a few swollen lymph nodes on the right side of her neck for the past 6 months, which were initially sore, but never painful. She endorsed drenching night sweats and a 20-pound weight loss over the last 6 months, but denied any fever or chills. Her past medical history and family history were non-contributory. She is a cigarette smoker with a 10 pack-year history of cumulative smoking. After a course of antibiotics that had no effect on her lymphadenopathy, she had a cervical lymph node excisional biopsy.

Given the presence of B symptoms, namely night sweats and 20-pound weight loss, I would favor an oncological condition such as lymphoma. The clinical picture is highly suspicious for Hodgkin lymphoma (HL), which has been associated with cigarette smoking based on a recent meta-analysis of epidemiological studies [1]. The differential diagnosis also includes follicular lymphoma (FL) and head and neck (H&N) cancer. FL, however, tends to present in older patients with B symptoms reported in only 20-30% of the cases. H&N cancer also tends to present in older individuals and has a strong male predominance. Given the 6-month clinical course, I would not favor more aggressive disorders such as Burkitt or diffuse large B-cell lymphoma.The hematoxylin and eosin sections demonstrated a polymorphic lymphoid population focally intersected by broad areas of fibrosis. The lymphoid infiltrate consists of small-to-medium-sized lymphocytes with a background of scattered eosinophils, histiocytes, and neutrophils. Occasional large binucleated hyperchromatic cells with prominent nucleoli (Reed-Sternberg cells) are noted within this infiltrate. Per immunohistochemistry, the Reed-Sternberg cells are positive for expression of CD30 and CD15, and negative for CD3, CD20, ALK-1, granzyme B, cytomegalovirus (CMV), Epstein-Barr virus, and herpes simplex virus. These findings are diagnostic of classical HL, nodular sclerosing (NS) variant.Not surprisingly, we have a pathological diagnosis of classical HL, NS variant. Although included in the group of classical HL, the NS variant is the most common, accounting for approximately 60% of the cases. The NS variant seems to be associated with a better prognosis than other variants such as mixed cellularity (MC) and lymphocyte-depleted (LD) HL. Based on a recent population-based study from the SEER database, patients with NS had higher relative survival and lower lymphoma-related death rates at 5 years than patients with MC or LD HL [2]. To complete this patient's staging and prognostic workup, a positron emission tomography/computed tomography (PET/CT) s...
