Anterior chamber metastasis from neuroblastoma.
An apparently normal 10-day-old girl had, since birth, a gray-white vascularized tumor in the inferior quadrants of the right anterior chamber. General physical examination revealed abdominal distension, hepatomegaly, splenomegaly, and a deeply located abdominal mass. Multiple subcutaneous nodules scattered all around the body's surface could be palpated. Surgical exploration confirmed the presence of a left adrenal neuroblastoma. Six months after a complete resection of the abdominal tumor and general radiotherapy and chemotherapy, the right anterior chamber mass regressed almost completely, leaving only a calcified residue. The child is living and well six years after the diagnosis of neuroblastoma. This is the first case known to us in the literature of a congenital anterior chamber metastasis, as well as the first case reported of an anterior segment metastasis from a neuroblastoma.

Muscular structural changes following fadenoperation.
The authors describe the macroscopic, histological, and ultrastructural findings observed in an experimental animal model of the fadenoperation . Grossly, muscular fibrosis and musculo-scleral adhesions were well established after the second postoperative month. Histologic findings demonstrated the development of a granulomatous, foreign body reaction around the musculo-scleral fixation suture, collagenization of the muscle tissue from the first postoperative month and degenerative phenomena in the muscle fibers. Electron transmission microscopic study showed atrophy and angulation with distortion of the myofibrillar matrix, along with alteration of the Z bands of muscle fibers, mitochondrial alteration, and dilatation of the sarcotubular system. All these experimental findings suggest the relative irreversible effects of the fadenoperation after the early postoperative period and for the first time, demonstrated that this surgical technique alters the muscle structure.
