Malignant epithelial cells were noted within the sarcolemmal sheath of skeletal muscle fibers in a case of recurrent laryngeal carcinoma. Literature is reviewed to evaluate the diagnostic and prognostic significance of this rare intramyofiber skeletal metastasis by cancer cells.

We report on a 56-year-old man who had two distinct and separate primary tumors of the bladder simultaneously: one mucin-producing adenocarcinoma and the other a transitional cell carcinoma. Despite local extension of the adenocarcinoma beyond the bladder wall, surgical resection has resulted in a 6-year recurrence-free survival of the patient.
An intraspinal epidermoid cyst occurring in the lumbo-sacral region of a 38-year old man with congenital spina bifida occulta is described. Relevant literature on the subject is reviewed.
A case of a large localized fibrous mesothelioma of pleura is described and the literature is reviewed. The histogenesis of this rare tumor is discussed.
We studied 43 cases of reexcised skin where a diagnosis of "inadequately excised basal cell carcinoma" was made at the initial excision. Only 3 cases (7%) revealed microscopic residual tumor. Prior studies have shown a recurrence rate as high as 35% for "inadequately excised basal cell cancers." Possible reasons for relatively low incidence of residual tumor in the reexcised specimens are discussed.
A case of duodenal lipoma causing massive hemorrhage is described. Literature on the subject is reviewed.
The so-called idiopathic scrotal calcinosis does not appear to be idiopathic, but rather a process of dystrophic calcification of epidermal cysts. We report a case that would be otherwise called "idiopathic" where we found squamous epithelial lining around the calcified masses. Literature is reviewed in support of the view that the calcified scrotal nodules are related to epidermal cysts.
An unusual scrotal mass occurring in a 72-year-old man is described. Clinically and grossly, the lesion appeared to be a neoplasm. However, microscopically the mass was composed of fibromyxomatous tissue that appeared to be degenerative rather than neoplastic in nature.

Plasma cell granuloma (inflammatory pseudotumor) has been described most commonly in the lung. Review of the English literature fails to reveal occurrence of such a lesion in the tonsil. We are reporting such a case presenting as a unilateral tonsillar mass in a 63-year-old man. A more typical case of plasma cell granuloma of lung is also presented to illustrate the similarity between the tonsillar and pulmonary lesions.
A case of prostatic adenocarcinoma metastasizing to the epididymis is described, and the literature is reviewed.
