BACKGROUND: Lung cancer is the most commonly diagnosed neoplasm in humans, however this does not apply to other animal species. Living in an aquatic environment the respiratory system of cetaceans had to undergo unique adaptations in order to them to survive and cope with totally different respiratory pathogens and potentially carcinogens from those affecting humans. CASE PRESENTATION: This article discusses not only macroscopical, histopathological and immunohistochemical features of a pulmonary carcinoma with disseminated metastases in a long-finned pilot whale (Globicephala melas), as well as the immunohistochemical analysis performed on various tissues of cetaceans belonging to the genus Globicephala...

We present a rare case of silent giant pheochromocytoma with leukemoid reaction which has not been reported before. The patient was a 61-year-old woman who complained of progressive weight loss for 3 months. Preoperative the urine VMA was 105.54mg/24h. WBC count was 56.9x10(9)/L. Abdominal ultrasound and CT revealed a mass measured 18×11cm in the left adrenal area. The patient underwent the adrenal gland neoplasm resection. Postoperative histopathologic evaluation confirmed the diagnosis of pheochromocytoma...

AIM: Ganglioneuroma (GN) is the most uncommon and the most benign tumor among neuroblastic neoplasms, and in 29.7% of cases it finds in an adrenal gland. Usually asymptomatic, this tumor is detected incidentally in the majority of cases. It is generally challenging to obtain a precise diagnosis of adrenal ganglioneuroma (AGN) before surgery. Misdiagnosis rate of AGN on CT and MRI is 64.7% and clinicians and surgeons are often lacking in knowledge of this rare disease. For this reason, we pointed out the clinical, biochemical, radiologic and pathologic features of AGN in an our experience, with the aim to find out if there are some features able to facilitate a preoperative diagnosis...

As certain strains of mice age, hyperplastic lesions resembling gonadal tissue accumulate beneath the adrenal capsule. Gonadectomy (GDX) accelerates this heterotopic differentiation, resulting in the formation of wedge-shaped adrenocortical neoplasms that produce sex steroids. Stem/progenitor cells that reside in the adrenal capsule and retain properties of the adrenogonadal primordium are thought to be the source of this heterotopic tissue. Here, we demonstrate that GLI1(+) progenitors in the adrenal capsule give rise to gonadal-like cells that accumulate in the subcapsular region...

Clouded leopards in North American zoological institutions have a high frequency of pheochromocytomas and were identified in 32 of 70 (45%) animals necropsied. Archival sections of adrenal gland from 20 adult clouded leopards with unilateral or bilateral pheochromocytomas collected between 1984 and 2011 were examined by light microscopy and immunohistochemistry, and case demographics were reviewed. Affected leopards were older than 10 years of age (mean, 16 years; range, 11-19 years), and males were overrepresented (12 males, 8 females)...

In the normal human adrenal gland, steroid secretion is regulated by a complex network of autocrine/paracrine interactions involving bioactive signals released by endothelial cells, nerve terminals, chromaffin cells, immunocompetent cells, and adrenocortical cells themselves. ACTH can be locally produced by medullary chromaffin cells and is, therefore, a major mediator of the corticomedullary functional interplay. Plasma ACTH also triggers the release of angiogenic and vasoactive agents from adrenocortical cells and adrenal mast cells and, thus, indirectly regulates steroid production through modulation of the adrenal blood flow...

Steroid cell tumor not otherwise specified (NOS) is a rare subtype of sex cord stromal tumor of the ovary and contributes less than 0.1% of all ovarian neoplasms. The majority of tumors occur in pre-menopausal women (mean age: 43 years), in which 56-77% of patients present with virilization due to excess testosterone. An 80-year-old woman with worsening alopecia and excessive growth of coarse hair on abdomen and genital area was found to have elevated serum testosterone level (462 ng/mL). Radiologic studies were consistent with bilateral adrenal adenomas...

Oncocytic neoplasms are tumors composed predominantly or exclusively of oncocytes (large polygonal cells with granular eosinophilic cytoplasm due to abnormal mitochondrial accumulation). These tumors are frequently reported in the thyroid, kidneys, and salivary glands. However, they are distinctly rare in the adrenal cortex. Oncocytic adrenocortical neoplasms (OAN) are classified regarding their biological behavior by their histological features according to the Lin-Weiss-Bisceglia system (LWB). Here, we report a case of OAN of borderline or uncertain malignant potential (BMP) with subsequently identified papillary thyroid carcinoma (PTC)...

A 74-year-old man presented with right flank pain and a palpable mass in the left flank. Blood pressure was normal. Contrastenhanced computed tomography (CT) showed a 17 × 16 × 12 cm retroperitoneal mass over the left kidney, solid and heterogeneous. There were also 3 retro aortic lymph nodes and bilateral renal lithiasis. Twenty four-hour urinary metanephrines and normetanephrines were normal. The patient underwent a resection of the mass with left adrenalectomy by a lumbar incision. Histological findings revealed an adrenal oncocytic neoplasm (AON) with uncertain malignant potential...

The current WHO classification of neuroendocrine tumors (NET) differentiates between typical carcinoids (low grade NET), atypical carcinoids (intermediate grade NET) and small cell and large cell carcinomas (high grade NET) according to the prognosis. Neuroendocrine neoplasms (NEN) of the gastrointestinal tract and the pancreas are graded in an identical way. Together with the TNM system this enables a preoperative estimation of the prognosis in biopsies and fine needle aspirates. Well-differentiated tumors are graded into G1 tumors by the number of mitoses, <2 per 10 high-power fields (HPF) and the Ki-67 (index <3 %) and G2 tumors (2-20 mitoses/10 HPF, Ki-67 3-20 %)...

Adrenocortical carcinomas are relatively rare, but they are considered to be highly aggressive malignant tumors. Sarcomatoid carcinomas represent an even more aggressive type. Bilateral malignant adrenal tumors are extraordinary rare, except for those that represent metastatic spread from a primary neoplasm. Here we report a case of a 69-year-old woman who presented symptoms that raised strong suspicions of adrenal insufficiency. Bilateral adrenal masses, identified in the imaging study, were responsible for the clinical manifestation and surgically resected...

Neuroendocrine tumors (NETs) and ectopic adrenocorticotropic hormone (ACTH) syndrome are frequent in adult patients. However, primary intracranial NETs, exhibiting immunonegativity for ACTH, high serum ACTH level and treated with anterior skull base reconstruction, are rare and complicated. We herein present a case of a primary intracranial NET immunonegative for ACTH, resulting in ectopic ACTH syndrome. A 40-year-old woman presented with intermittent rhinorrhea, rapid weight gain, polydipsia, polyuria, hypertension, dimness, bilateral exophthalmus, diminution of vision in the left eye and pigmentation of the skin of the face and trunk...

BACKGROUND: The use of minimally invasive procedures in autopsies such as image-guided fine-needle aspiration may facilitate family acceptance and, therefore, increase the number of postmortem examinations. The objective of the current study was to validate the use of cytology in a prospective set of conventional autopsies. METHODS: All lesions and organs sampled for histological examination were concomitantly evaluated by scrape cytology of exactly the same location...

A small proportion of patients with chronic lymphocytic leukemia (CLL) may progress to large cell lymphoma, or Richter syndrome (RS). The large cells of RS may arise through transformation of the original CLL clone (clonally related) or represent a new neoplasm (clonally unrelated), which might be Epstein-Barr virus (EBV)-associated. We present a 61-year-old male with 5-year history of CLL who developed RS on bilateral adrenal glands. The tumor showed a vague nodular growth pattern separated by thick fibrous bands and the tumor cells were large and pleomorphic, with focal sheet-like growth pattern, in a background of small B and T-lymphocytes...

Thymic neuroendocrine carcinoma (NEC) is a rare type of cancer. Unlike other thymic epithelial tumors and carcinoids originating in other locations, thymic NEC possesses a more aggressive biological behavior, including invasion to proximal structures, local recurrence and distant hematogenous metastasis. Distant metastasis is often observed in the bones, lungs, spleen, liver and adrenal glands. However, pancreatic metastasis resulting from thymic NEC is extremely uncommon, and only a few cases of patients with this disease have been reported...
