TABLE 4.

Classification of in-transit metastatic patterns defined by localization of primary melanoma.

	Foot (n = 15)	Lower leg (n = 31)	P-value
Full match	3 (20%)	22 (71%)
Partial match	6 (40%)	2 (6%)	0.007
No match	6 (40%)	7 (23%)

Depending on the occurrence of in-transit metastases in the corresponding anatomical area of the primary melanoma, metastatic patterns are classified as full match (≥90%), partial match (<90% and ≥50%), or no match (<50%). While in melanoma of the lower leg the majority of in-transit metastases develop in the corresponding lymphatic drainage areas, melanoma of the foot shows a different metastatic pattern.
