Abstract
The INHAND (International Harmonization of Nomenclature and Diagnostic Criteria for
Lesions in Rats and Mice) Project (www.toxpath.org/inhand.asp) is a joint initiative among
the Societies of Toxicological Pathology from Europe (ESTP), Great Britain (BSTP), Japan
(JSTP) and North America (STP) to develop an internationally accepted nomenclature for
proliferative and nonproliferative lesions in laboratory animals. The purpose of this
publication is to provide a standardized nomenclature for classifying microscopic lesions
observed in the endocrine organs (pituitary gland, pineal gland, thyroid gland,
parathyroid glands, adrenal glands and pancreatic islets) of laboratory rats and mice,
with color photomicrographs illustrating examples of the lesions. The standardized
nomenclature presented in this document is also available electronically on the internet
(http://www.goreni.org/). Sources of material included histopathology databases from
government, academia, and industrial laboratories throughout the world. Content includes
spontaneous and aging lesions as well as lesions induced by exposure to test materials. A
widely accepted and utilized international harmonization of nomenclature for endocrine
lesions in laboratory animals will decrease confusion among regulatory and scientific
research organizations in different countries and provide a common language to increase
and enrich international exchanges of information among toxicologists and
pathologists.

Abstract
The 2014 annual National Toxicology Program (NTP) Satellite Symposium, entitled "Pathology Potpourri" was held in Washington, D.C., in advance of the Society of Toxicologic Pathology's 33rd annual meeting. The goal of this annual NTP Symposium is to present current diagnostic pathology or nomenclature issues to the toxicologic pathology community. This article presents summaries of the speakers' presentations, including diagnostic or nomenclature issues that were presented, along with select images that were used for audience voting and discussion. Some lesions and topics covered during the symposium included a pulmonary mucinous adenocarcinoma in a male B6C3F1 mouse; plexiform vasculopathy in Wistar Han (Crl:WI[Han]) rats; staging of the estrous cycle in rats and mice; peri-islet fibrosis, hemorrhage, lobular atrophy and inflammation in male Sprague-Dawley (SD) rats; retinal dysplasia in Crl:WI[Han] rats and B6C3F1 mice; multicentric lymphoma with intravascular microemboli and tumor lysis syndrome, and 2 cases of myopathy and vascular anomaly in Tg.rasH2 mice; benign thymomas in Crl:WI[Han] rats; angiomatous lesions in the mesenteric lymph nodes of Crl:WI[Han] rats; an unusual foveal lesion in a cynomolgous monkey; and finally a series of nomenclatures challenges from the endocrine International Harmonization of Nomenclature and Diagnostic Criteria (INHAND) Organ Working Group (OWG).

Abstract
Vacuolar degeneration of the thyroid follicular epithelium was observed in two untreated
female cynomolgus monkeys assigned to control groups. In light microscopy, large vacuoles
containing a homogenous substance occupied the basal region of the epithelium, and the
nuclei had shifted toward the apical region. The vacuoles showed negative reactions to PAS
and thyroglobulin. Electron microscopic observation revealed dilatation of the rough
endoplasmic reticulum corresponding to the vacuoles. The plasma TSH, T3 and T4 levels
determined for the samples kept frozen were within the normal ranges, suggesting that the
thyroid function was kept intact.

Abstract
Adenomatous polyposis coli (APC) is a multifunctional protein as well as a tumor suppressor. To determine the functions of the C-terminal domain of Apc, we have investigated Apc ( 1638T/1638T ) mice, which express a truncated Apc that lacks the C-terminal domain. Apc ( 1638T/1638T ) mice are tumor free and exhibit growth retardation. In the present study, we analyzed the morphology and functions of the thyroid gland in Apc ( 1638T/1638T ) mice. There was no significant difference in the basal concentration of serum thyroid hormones between Apc ( 1638T/1638T ) and Apc (+/+) mice. Thyroid follicle size was significantly larger in Apc ( 1638T/1638T ) mice than in Apc (+/+) mice. The extent of serum T4 elevation following exogenous thyroid-stimulating hormone (TSH) injection was lower in Apc ( 1638T/1638T ) mice than in Apc (+/+) mice. TSH also induced a greater reduction in thyroid follicle size in Apc ( 1638T/1638T ) mice than in Apc (+/+) mice. Analyses using immunohistochemistry and electron microscopy indicated that follicular epithelial cells in Apc ( 1638T/1638T ) mice had an enlarged rough endoplasmic reticulum of irregular shape. These results suggest that the C-terminal domain of Apc is involved in thyroid morphology and function.

Abstract
Septate cytoplasmic vacuoles, which are one of the cytologic findings characteristic of papillary thyroid carcinoma, are small, uniform, and well-defined vacuoles, with defined strands of cytoplasm separating them. We report on a case with histologic and ultrastructural findings corresponding to septate cytoplasmic vacuoles, which have not been previously described. The patient was a 51-yr-old man with a mass in the left anterior of the neck, measuring 4.0 x 3.5 cm in diameter. Aspiration cytology smears revealed findings typical of papillary thyroid carcinoma, including papillary tissue fragments, intranuclear inclusions, nuclear grooves, powdery chromatin, and psammoma bodies. The tumor cells which were located at the periphery of small three-dimensional clusters, and others which showed a sheet-like arrangement, demonstrated uniform, small vacuoles in relatively abundant, dense cytoplasm. Histologically, a small number of papillary thyroid carcinoma cells with multiple vacuoles were observed, which were limited to the hobnail-shaped cells located at papillary configurations or floating tumor cells within the papillary lumen. Ultrastructurally, the hobnail-shaped tumor cells demonstrated various-sized dilated rough endoplasmic reticulum and rich heterochromatin. We emphasize that septate cytoplasmic vacuoles correspond to dilated rough endoplasmic vacuoles and are probably related to degenerative changes.
