Few large series compare lymphomas of the nasal cavity with those of the pa
ranasal sinuses. We studied the cases of 58 patients, 34 males and 24 femal
es, aged 7 to 92 years (mean, 57 years), who had lymphoma involving the nas
al cavity or paranasal sinuses. Thirty-three patients had diffuse large B-c
ell lymphoma (DLBCL). Twenty-three were male and 10 were female, with an ag
e range of 7 to 91 years (mean, 63 years); two were HIV-positive. Only 2 of
11 cases tested tone in an HIV-positive patient and one of lymphomatoid gr
anulomatosis type) were Epstein-Barr virus (EBV)-positive. Thirty (91%) inv
olved paranasal sinuses, 10 with nasal involvement, whereas three cases had
nasal, but not sinus, involvement. At last follow-up, 16 (67%) were free o
f disease 7 to 169 months later (mean, 65 months), and 8 (33%) had died of
disease 2 to 166 months later (mean, 45 months). Seventeen patients had nas
al-type natural killer (NK)/T-cell lymphoma. There were 10 women and 7 men,
aged 27 to 78 years (mean, 48 years). Thirteen of 14 were EBV-positive. Si
xteen patients had nasal involvement, eight with sinus involvement. Eleven
(73%) of 15 were alive and well 6 to 321 months later(mean, 139 months), th
ree (20%) died of lymphoma 1, 11, and 12 months later, and one (7%) is aliv
e with disease. There was one case each of marginal zone B-cell lymphoma, B
urkitt's lymphoma, Burkitt-like lymphoma, peripheral T-cell lymphoma of uns
pecified type, and adult T-cell lymphoma/leukemia. In an additional three c
ases, the lymphomas were composed predominantly of large cells, but no immu
nophenotyping could be performed for subclassification. In 19 cases (17 DLB
CLs, 1 Burkitt-like lymphoma, and 1 lymphoma of uncertain Lineage), present
ing symptoms included complaints related to the eyes. In 16 cases (13 DLBCL
s, 1 Burkitt-like lymphoma, 1 nasal NK/T-cell lymphoma, and 1 lymphoma of u
ncertain lineage), the orbit was invaded by lymphoma. In our series, the mo
st common lymphoma to arise in the sinonasal area is DLBCL, followed by nas
al NK/T-cell lymphoma. Comparison of these two types of lymphoma showed tha
t lymphomas involving sinuses without nasal involvement were predominantly
DLBCLs (20 of 21), whereas nasal cavity lymphomas without sinus involvement
were usually NK/T-cell type (8 of 11) (p = 0.000125). Compared with patien
ts with DLBCL, patients with nasal NK/T-cell lymphoma were overall younger,
with a lower male-to-female ratio. Lymphomas of B-cell lineage were more l
ikely to be associated with symptoms related to the eyes (p < 0.0005) and t
o have extension to the orbit (p < 0.01) than were lymphomas of T- or NK-ce
ll lineage. In contrast to results of Asian studies in which nasal NK/T-cel
l lymphoma has a very poor prognosis, our nasal NK/T-cell lymphomas had an
outcome similar to that of DLBCL.
