Pseudocarcinomatous hyperplasia associated with hidradenoma papilliferum.

Cutaneous pseudocarcinomatous hyperplasia is a benign proliferation that can be associated with many nontumoral and tumoral conditions. In the literature, squamous proliferations of different types have been associated with several types of adnexal adenomas. However, we found no reported case of association of hidradenoma papilliferum with pseudocarcinomatous hyperplasia.

Areolar sebaceous hyperplasia with underlying primary duct carcinoma of the breast in a woman with Donohue syndrome (leprechaunism).

Areolar hyperplasia is only reported when exaggerated, and even so, exaggerated areolar sebaceous hyperplasia is rare. We have recently seen a case of areolar sebaceous hyperplasia in a 32-year-old woman with Donohue syndrome (leprechaunism), who also had an invasive ductal carcinoma in the same breast. The patient showed typical "elfin-like" face with wide nostrils and thick lips, large and low-set ears, and dysplastic nails.

Granulomatous response due to anabolic steroid injections.

Injected corticosteroids can sometimes lead to a granulomatous reaction. This is apparently also true for anabolic steroids, which are often used by bodybuilders, although we have not found any histologic report on such a phenomenon. We report a case of a granulomatous reaction in a 30-year-old male bodybuilder having undergone anabolic steroid injections.

Study of the immunoexpression of Bcl-2 by a cutaneous granular cell tumor.

Background: Cutaneous granular cell tumors have only rarely been examined for Bcl-2, a marker that is expressed by granular cell tumors from other parts of the body.

Objective: We retrospectively studied three cases of cutaneous granular tumors from our archives.

Methods: We immunohistochemically tested for neuron-specific enolase (NSE), CD68 (KP1), Bcl-2, and S-100.

[Mucinous adenocarcinoma of the appendix associated with ovarian tumors and pseudomyxoma peritonei. The difficulty in differential diagnosis].

Mucinous adenocarcinoma of the appendix is rare. If there is a concomitant ovarian tumor to determine the primary might be difficult. Histological features are not always determinant, but there are some macroscopic findings that may suggest an origin in the appendix.

[Amebic liver abscesses with bacterial superinfection in a nonendemic area].

A 26-year-old man was admitted to hospital with asthenia, weight loss, right upper quadrant abdominal pain, diarrhea without blood, and fever. Abdominal ultrasonography showed multiple hypoechoic areas in the left hepatic lobe. On abdominal CT, multiple hypodense areas without contrast capture were consistent with hepatic abscesses.

Chondroid metaplasia in the tunica media of the aorta in dogs submitted to saphenous vein aorto-cava by-pass.

We submitted twelve dogs to aorto-superior vena cava by-pass with saphenous vein. Six months later, all dogs had developed areas of chondroid metaplasia in the tunica media of the aorta, near the area of anastomosis. Three dogs also had bony metaplasia.

[Primary malignant melanomas of the nasal fossae].

Melanoma of the nasal and paranasal sinus mucosa represented less than 1% of all melanomas. Melanoma to be localized commonly in nasal septum and your prognosis is poor. We presented three cases with a mean age of 75 years.

Inflammatory metastatic carcinoma. A clinical and histopathologic study of three cases.

The inflammatory metastatic carcinoma is a rare clinical entity, histologically characterized by lymphatic dermal invasion by neoplastic cells. We report three cases of inflammatory metastatic carcinoma, two of them secondary to a breast carcinoma, and the third secondary to a colon adenocarcinoma.

[Histopathological features of carcinomas of the bladder treated with radiotherapy. Anatomo-clinical correlation].

We evaluated the effects of radiotherapy (total dose 6,100 rads; 1,500 intraoperative and 4,600 external irradiation) on urothelial carcinomas in 16 patients. Tumor response and the histopathological changes were evaluated. All but one of the patients were men.

Intraoperative and external beam radiotherapy in invasive bladder cancer: pathological findings following cystectomy.

The pathological findings observed following intraoperative radiotherapy (IORT) boost (15Gy) to the whole bladder, external beam fractionated irradiation (46Gy in 5 weeks), and planned radical cystectomy in patients with deep invasive bladder carcinoma are analyzed. Clinical pretreatment stage of disease was T3 (16 cases) and T4 (two cases). No evidence of residual tumor (pT0) was demonstrated in 11 cystectomy specimens (61%) and residual tumor (pT+) was observed in seven (39%).

[Papillomas of the esophagus: presentation of 5 cases and review of the literature].

Papilloma of the esophagus is an uncommon benign tumor. We report five cases, four diagnosed by gastroscopy and one on autopsy. Three were women and two men.

Cyanamide and its calcium form: do they differ with respect to their action on the liver cell? Experimental study in the rat.

Cyanamide is a drug frequently used as aversion therapy in chronic alcoholism. A chronic hepatocytic lesion induced by cyanamide has been described by a member of our team over the last few years. It consists of distinctive cytoplasmic inclusion bodies, similar to those observed in Lafora's disease.
