Seven patients with the co-occurrence of meningioma and pituitary adenoma are reported. Diagnosis was based on histological examination and if not available on MR imaging. Extensive review of the literature reveals only 18 other cases with this association if meningiomas appearing after radiation therapy for pituitary tumors are excluded. As in isolated meningiomas, the female-to-male ratio is high. A preponderance of perisellar meningiomas is apparent. Another distinct characteristic of this combination is not revealed, since no specific typing of the meningioma and no specific endocrine syndrome is uncovered. Two patients presented with multiple meningiomas, of which one showed two histologically different tumor types. The presence of other tumors in association with pituitary adenomas and meningiomas in our series is striking and could suggest a genetic dysregulation leading to the development of these tumors.

Skin biopsies were performed in two cases of infantile generalized ceroidlipofuscinosis. In the first case the biopsy was done at the age of 8 years and the diagnosis was confirmed shortly thereafter by a postmortem examination. In the second case, the biopsy was performed much earlier (27 months) at a time when the diagnosis was not suspected; it was subsequently confirmed by similar findings in a neuro-muscular biopsy. In both cases, numerous cytoplasmic inclusions with granular osmiophilic deposits were present in epidermal cells, eccrine sweat glands, smooth muscle cells, nurve fascicles, fibroblasts and vascular elements while none were found in age-matched controls. As already stressed by Anzil et al. (1975), the morphology of the inclusions can be heterogeneous and linear profiles were often observed, mainly in the cytosomes present in the vascular cells. We feel confident that a diagnosis of infantile generalized ceroid-lipofuscinosis can be made by skin biopsy obviating therefore the need for other surgical procedures.
