Ultrastructural studies were carried out on the invasive nodule of forty malignant melanomas. The findings support the concept that the fine structure of lentigo maligna melanoma is often characteristic, and differs from that of superficial spreading and nodular melanoma. The melanosomes in lentigo maligna melanoma are usually ellipsoidal and resemble those of normal melanocytes, whereas the melanosomes in superficial spreading and nodular melanoma are most often spheroidal and abnormal in appearance. Superficial spreading and nodular melanomas cannot be distinguished reliably by their ultrastructure. Melanosomal appearances could not be related to the presence of a pre-existing
naevus
or the depth of invasion of the tumour nodule.

An autosomal dominant genodermatosis that is characterized by painful callosities develops over pressure points. Histologically, these lesions are similar to epidermal
nevi
.

Distinctive melanocytic moles are described in 37 patients from six melanoma families. Among the family members examined by the authors, 15 of 17 patients with melanoma and 22 of 41 nonmelanoma relatives had the unique moles. The clinical and histological features of these moles have been designated the "B-K
mole
syndrome." The clinical features of the syndrome include the presence of less than 10 to greater than 100 moles prominent of the upper trunk and extremities, and variability of
mole
size (5 mm to 15 mm), outline, and color combination. Histologically, B-K moles show atypical melanocytic hyperplasia, lymphocytic infiltration, delicate fibroplasia, and new blood vessels that occur within a compound nevus or de novo. The transformation of two B-K moles into malignant melanomas was documented photographically.

A 41-year-old man developed squamous-cell carcinoma within a verrucous
nevus
of linear distribution of a long duration. Controversial cases have been reported in the literature. Such malignant change in verrucous
nevus
is extremely rare.

A 59-year-old woman had thick plaques of leukoplakia on the tongue bilaterally. The condition was initially diagnosed by biopsy as a white-sponge
nevus
. A second biopsy of a suspicious area on the right side showed squamous-cell carcinoma two years later. It is speculated that prednisone therapy for steroid-dependent intrinsic asthma may have caused a loss of "immunologic surveillance," which permitted development of malignancy in a previously benign condition.

Speckled lentiginous nevus is, we feel, a distinctive nevocytic disorder and a clinical variety of
nevus
-cell
nevus
. The speckled areas show varying histological patterns that range from
nevus
incipiens to junctional and compound
nevi
. The background shows histological features of lentigo simplex. It is our contention that speckled lentiginous
nevus
should be separated from
nevus
spilus and
nevus
spilus tardus (Becker's), which we consider to be variants of epidermal
nevus
.

Noonan's syndrome is a multisystem syndrome that has received little attention in the dermatologic literature, although there are numerous cutaneous manifestations that have been described. A typical case of Noonan's syndrome is presented. Clinical findings in this patient included short stature, curly scalp hair, prominent ears, hypertelorism, webbing of the neck, cubitus valgus, pigmented
nevi
, stasis dermatitis, and plantar hyperkeratosis. The latter two findings have not been previously reported in Noonan's syndrome. We urge that dermatologists become more aware of this syndrome to document the spectrum of changes that may occur in Noonan's syndrome.

Melanoma specific protein is immunologically related to altered
naevus
cell cytoplasm. It is excreted by patients with malignant melanoma but in no other malignancy. The protein has been detected in patients with actively developing halo naevi but not when repigmentation is taking place. It also occurs in patients with very active vitiligo but in no other pigment condition we have studied. It is suggested that the protein is a marker of active destruction of
naevus
cells by immune mechanisms and that the release of toxic materials during this immune reaction may be responsible for the production of the halo phenomenon and for the areas of vitiligo that may be seen elsewhere on the skin.

A patient is presented with a rigid cavus deformity associated with a painful linear keratotic lesion on the lateral plantar border. A unilateral zosteriform lentiginous
naevus
is found on the same side as the foot deformity. Electrodiagnostic evaluation suggests the presence of a non-specific neuromuscular process on the affected side. This association has not previously been reported.

According to a popular system of classification, the term ichthyosis hystrix denotes an organoid epidermal
nevus
composed of hyperkeratotic papules with a bilateral distribution. Our patient had dramatic disfiguring epidermal changes of this type covering nearly all of her body. Although this abnormality began at the age of 2, she does not exhibit any of the various neurological or skeletal derangements that have been reported to be associated with the condition.
