The authors describe a solitary adenoma in a 5.5-year-old female Budgerigar (Melopsittacus undulatus). The tumour was partially blocking the lumen of the proventriculus and filled it almost completely. Decreased passage of food towards the gizzard and the intestines developed in the bird as result of the obstruction, which periodically hindered the passage, leading to slow emaciation. An epithelial tumour composed of irregular glandular acini was diagnosed by histological examination. Immunohistochemical reaction with pancytokeratin showed a positive cytoplasmic reaction both in the neoplastic and the normal glandular structures.

Solitary Adenoma

AbstractOne hundred and ten patients with primary hyperparathyroidism were studied, in which a normal parathyroid gland was found on the same side as an adenoma (both confirmed by histological examination), and the upper or lower location could clearly be defined during surgery. The distribution of the adenomas over the upper and lower glands was unequal: 61.8 per cent in the superior versus 38.2 per cent in the inferior position. Statistical analysis revealed that this is not a random distribution (p = 0.013). The explanation of this relative predilection is unknown. The finding should not influence the surgical procedure for primary hyperparathyroidism

The Primary Spermatocytes represent a stage in spermatogenesis when the first meiotic cell division occurs. They are derived from Spermatogonium or Stem cell through mitotic division. At the zygotene phase of meiotic prophase the Synaptonemal complex appears in these cells in the space between the paired homologous chromosomes. Spermatogenesis and sperm structure in fish have been studied at the electron microscope level in a few species? However, no work has yet been reported on ultrastructure of tilapia, O. niloticus, spermatozoa and spermatogenetic process. In this short communication we are reporting the Ultrastructure of Primary Spermatocytes in tilapia, O. niloticus, and the fine structure of synaptonemal complexes seen in the spermatocyte nuclei.

Benign Tumours

Cavernous hemangiomas are benign tumours of mesodermal origin. Even though various localizations of hemangioma have been described in the literature, its occurrence in the greater omentum is very rare. Only symptomatic hemangiomas are indicated for surgical treatment. There are case reports presenting resection or surgical removal of the greater omentum with hemangioma because of mechanical syndrome, consumption coagulopathy, bleeding, infection or suspicion of a malignancy. This article presents a case report of a patient operated on for a suspicion of carcinomatosis of the greater omentum. Histological examination found hemangiomatosis in the resected greater omentum.
