Malignant melanoma originating from intradermal nevi. A clinicopathologic entity.
Two cases of malignant melanoma arising in preexisting intradermal nevi without a junctional element are described. These cases and the two known to have been reported previously demonstrate similar clinical and morphologic findings. These include an innocuous gross appearance, a nodular growth pattern, and deep levels of invasion. It appears that the origin of the tumor in the dermis conceals malignant transformation. The consequent time lapse and the dermal position of the lesion favor deep penetration of the tumor prior to removal.

Retroperitoneal liposarcoma metastatic to scalp.
Metastasis of liposarcoma to the scalp occurred in a 50-year-old-man. Review of the literature disclosed no documented reports. Although cutaneous metastases from internal malignancies are of relative infrequent occurrence, such metastases may be limited to the scalp and a diagnosis can be established by a biopsy.

Histiocytosis X of the skin in an elderly man.
A diffuse truncal cutaneous eruption of six months' duration in a 76-year-old man is described. Light and electron microscopy revealed infiltration of the papillary dermis and overlying epidermis by histiocytic cells containing Langerhans granules, findings characteristic of histiocytosis X. The Langerhans cell as a probable cell of origin and unifying feature for the subtypes of histiocytosis X is discussed. It is suggested that with increased awareness of the variability of histiocytosis X, atypical presentations will be identified more frequently.
Malignant myelosclerosis simulating metastatic bone disease.
A case of malignant myelosclerosis is described in a patient with a previous breast carcinoma. The difficulty in differentiating this entity from metastatic bone disease is discussed.
Apocrine hidrocystoma of the shoulder.
An apocrine hidrocystoma of the shoulder of a 59-year-old woman is, to our knowledge, only the third reported case that arose outside of the head and genitalia. Its origin was nonetheless consistent with the distribution of apocrine glands in adults.
