Table 3. Mast cell density in relation to tumor cell density in CTCL variants.

Type of lymphoma	Mast cell density (Mast cells/total cells)
	Median (range)
CTCL	2,22 (0,15–6,74)
Mycosis fungoides	2,53 (0,45–6,74)
MF IA	3,54 (0,45–6,74)
MF IB	3,65
MF IIA	3,03
MF IIB	1,72 (0,69–3,29)
Sezary syndrome	(0,15;4,05)
LyP	1,45 (0,48–2,76)
SM	1,10 (0,22–1,58)
C-ALCL	0,37

CTCL = primary cutaneous T-cell lymphomas; MF = Mycosis fungoides; LyP = lymphomatoid papulosis; SM = primary cutaneous CD4⁺ small/medium sized pleomorphic T-cell lymphoma C-ALCL = primary cutaneous anaplastic large cell lymphoma;
