Vascular retardation in dormant growth-stunted malignant melanomas.
Progression and metastatic spread of primary cutaneous melanoma (PCM) is largely predicted by the thickness of the primary tumor. However, the accretive or proliferative pattern of growth of PCM is another aspect that might affect the prognosis. We retrieved from our histopathological files 11 superficial spreading PCM which had been documented to show an almost stable size for at least 3 years before excision. The area of the PCM at the skin surface had been measured by planimetry on the excision specimens. Histological sections were used to measure the maximum thickness of the neoplasms. A PCM volume estimate was derived by multiplying the surface area by the thickness of the tumors. In addition, the vessel area was determined beneath and outside the PCM lateral margins on Ulex europaeus agglutinin-1-stained sections using computer-assisted image analysis. Peritumoral vascularity was significantly more developed than at distance of the neoplasms. A significant negative exponential correlation was yielded between the peritumoral vascularity and the PCM volume estimate. Such vascular eclipse might be the cause of clinical PCM dormancy. However, other possible independent mechanisms are not ruled out by the present study.
