Summary of the Molecular Findings in the Noncutaneous Extranodal, Nodal, and PCFCL Patient Groups^*

	Extranodal FL N = 26 (%)	Nodal FL N = 40 (%)	PCFCL N = 8 (%)	P
MBR	8 (31)	13 (32)	3 (38)	NS
mcr	0	0	0	—
3′BCL2	4 (15)	1 (2)	1 (12)	0.04
5′mcr	1 (4)	0	0	NS
icr	7 (26)	4 (10)	1 (12)	0.048
Total PCR+	14 (54)	17 (42)	5 (63)	NS
t(14;18) −	12 (46)	23 (58)	3 (37)^†	NS
BCL6 translocation	1 (4)	3 (8)	N/A	NS

Eight cases contained double breakpoints.

^†

One PCFCL cases was t(14;18)-negative by PCR but did contain translocation by FISH.

FISH indicates fluorescence in situ hybridization; FL, follicular lymphoma; PCFCL, primary cutaneous follicle center lymphoma; PCR, polymerase chain reaction.
