Miliary pattern due to occupational lung disease in a patient with laryngeal cancer.

Inhalation of metal dusts and fumes can induce a wide range of respiratory disorders, including granulomatosis, chemical pneumonitis and pulmonary interstitial disease. Laryngeal cancer is the most common cancer of the upper aerodigestive tract. We present a patient with occupational lung disease whose chest CT showed miliary nodular pattern, with concurrent laryngeal cancer who had been engaged in type printing for 22 years. Histology of the laryngeal lession showed squamous cell laryngeal cancer. Histology of the nodules showed a foreign body granulomatous response with several foreign body cells, most probably due to exposure to numerous inorganic (lanthanides, elements such us La, Ce, Nd, Sm, EU, Tb, Lu) and organic particles (such us acrylates, epoxy- and urethane-acrylates).

Solitary fibrous tumor of the urinary bladder: report of a case with long-term follow-up and review of the literature.

Solitary fibrous tumor (SFT) is a neoplasm typically arising in the pleura. Yet, extrapleural cases have been described and are a common cause of diagnostic pitfalls, especially when met in unusual sites. We report the clinical and pathological features of a case of SFT arising in a rather unusual site, the urinary bladder, the seventh reported to date in the English literature and the first with long term follow-up. Differential diagnosis from other spindle cell neoplasms of the bladder can be problematic. Prognosis of this neoplasm is obscure and long-term follow-up is required for all cases of solitary fibrous tumor. Solitary fibrous tumor is a rare mesenchymal tumor of the urinary bladder, but should always be considered in the differential diagnosis of spindle cell neoplasms encountered in the lower genital tract.

Fetus amorphous acardious: report of a rare case and differential diagnosis from placental teratoma with review of the literature.

Fetus amorphous acardious is a rare fetal malformation, lacking a functional heart and bearing no resemblance to human embryos. The main differential diagnosis is with placental teratoma and is based on the degree of skeletal organization and umbilical cord formation. A 27-year old woman delivered a healthy newborn at 37 weeks' gestation. An amorphous mass, covered with healthy looking skin, was connected to the placenta with a short pendicle. X-ray examination of the mass revealed the presence of vertebral column associated with ribs and pelvic bones. Histopathologic examination demonstrated the presence of spinal tube inside the vertebral column. Microscopy of the pedicle was consistent with umbilical cord. Various other tissues were also discovered, such as adipose tissue, gastric and large.
