Case 9 Female, 47 years. Small, dark papule, skin of cheekShow diagnosis & comments
Deep penetrating naevus of sun-damaged facial skin
In sun-damaged facial skin, it is wise to be cautious when ta melanocytic neoplasm displays unusual features. However, in this case, the slightly enlarged and cytoplasm-rich, lightly pigmented cells, which show a tendency to cluster together in small groups centered around a hair folliucle, and that do not disturb the archtecture of the uinvolved skin, are considered typical of deep penetrating naevus, so that a diagnosis of MELTUMP (melanocytic tumour of uncertain malignant potential) - or worse - can be avoided.
A small intermingled dermal common acquired naevus-component is also present.
