melanoma, malignant, acrolentiginous. reddish, partly skin-coloured, slowly growing, coarse plaque, which has predominantly displaced the nail bed. there are also bizarre, black-brown hyperpigmentations. the nail plate is no longer existent except for a rest.
Melanoma, malignant, acrolentiginous. solitary, chronically stationary, slowly increasing, localized at the right big toe, measuring approx. 0.5 cm, touch-sensitive, red node ulcerated with a dark pigmented part (see circle and arrow marking) Histology: tumor thickness 2.7 mm, Clark level IV, pT3b N0 M0, stage IIB.
Amelanotic acrolentiginous malignant melanoma: slowly growing nodule known for several years; increasing nail destruction in the last six months, also weeping and bleeding, sometimes slight pain; encircled and marked with an arrow, deep-seated pigment remains, which suggest the diagnosis "malignant melanoma".
Melanoma, malignant, acrolentiginous. 2 x 3 cm diameter, red, flat, slightly putrid ulceration on the right big toe of a 73-year-old woman. At the lateral border of the ulcer there are shadowy pigment remains (circled and marked with arrows) in intact skin. In addition, palpation of the peripheral venous leg stations on the right inguinal side shows several enlarged venous leg ulcers (DD: reactive enlargement?).
Dorsal cyst, mucoid: painless, approximately 1.5 cm large, skin-coloured, plump, elastic, surface-smooth "node" (cyst), which has existed for about 1 year, from which a gelatinous substance has emptied itself under pressure, whereby the whole node has disappeared. rezdiv within a few weeks

Melanoma, malignant, acrolentiginous.Here: amelanotic malignant melanoma: Chronic inpatient tumor in an 80-year-old patient, existing since 2 years, localized at a pressure-exposed site, flat, sharply defined, slightly painful, similar to an ulcer, slightly raised, flat, ulcerated. The diagnosis as primary tumor was made by finding a metastasis. Note: The diagnosis of malignant melanoma in the presented case can only be made histologically. Clinically, at best, a suspected malignant tumor can be made, which must be clarified histologically.
Angiosarcoma, epitheloid. condition after surgical removal of the nail for tissue sampling. bleeding tumour grown under the big toe nail, livid to brownish-red. rapid organ metastasis with lethal outcome within 6 months.
melanoma malignes acrolentiginous. dark discoloration of the right small toe existing for years. growth of thickness for 1/2 year, discoloration increasingly decreasing. now: largely amelanotic, centrally ulcerated and macerated nodule at the 5th toe. remark: treated as mycosis for several months.
