We report a case of a 74-year-old female with myxoid adrenocortical adenoma which showed different magnetic resonance imaging findings compared to those of a typical adrenocortical adenoma. The myxoid change in the adrenocortical adenoma is a rare form of degeneration. It presents a considerable diagnostic challenge to both radiologists and clinicians because it can mimic other adrenal tumor types on imaging. The MRI findings of the presented case included a high signal intensity on T2-weighted images similar to that of fluid and delayed progressive enhancement.

5.Pulmonary Pleomorphic Adenoma: Report of a Rare Case.
The Korean Journal of Internal Medicine 2007;22(2):122-124
Primary pleomorphic adenoma of the lung is a type of pulmonary adenoma that is extremely rare, and it predominantly occurs in the proximal airway. We recently experienced a case of a peripheral solitary pulmonary nodule that was discovered on the CT scans. We performed wedge resection with video-assisted thoracoscopic surgery and we firmly diagnosed this lesion as pulmonary pleomorphic adenoma according to the histology. We report here on a rare benign tumor that was diagnosed as a primary pleomorphic adenoma located in the lung periphery.

To investigate the diagnosis and surgical treatment of adrenocortical oncocytoma. The clinical data from three cases of adrenocortical oncocytomas (ACOs) were retrospectively analyzed and discussed in light of the relevant literature. In these three cases, one presented with virilization, while the other two cases had no typical clinical features. The tumor was completely encapsulated and was non-invasive. Microscopically, the tumor cells showed neither mitosis nor necrosis, with abundant eosinophilic cytoplasm. No recurrence or metastasis was discovered after close follow-up observation for 12-24 months. Adrenocortical ACOs are rather rare, and most of them are benign. It was hard to make a confirmed diagnosis of ACOs before surgery. Resection of tumor is the best choice, and close follow-up observation is essential.

OBJECTIVETo investigate clinicopathological characteristics of colorectal sessile serrated adenoma/polyp (SSA/P) and its differential diagnosis from other serrated lesions.
METHODSClinicopathological features of all cases of colorectal serrated lesions from 5 209 colorectal biopsy samples at Shanghai Tongji Hospital from 2008 to 2013 were reviewed. Three hundred and fifty-three cases of serrated lesions were erolled in the study. Morphological features of SSA/P were investigated with an emphasis on histologic criteria for diagnosis and a literature review was performed.
RESULTSThree hundred and fifty-three cases of serrated lesions were identified, including 25 SSA/P (7.1%), 278 hyperplastic polyp (HP, 78.8%), and 44 traditional serrated adenoma (TSA, 12.5%). Twenty-five patients with SSA/P consisted of 16 males and 9 females with a mean age of 62.2 years (aged 34-84 years) and the lesions involved sigmoid colon (14 cases), ascending colon (9 cases), rectum (1 case) and transverse colon (1 case). Grossly, the majority of SSA/P was sessile with an averaged size of 0.73 cm. Histologically, typical SSA/P had elongated crypts with prominent serration and distorted crypts architecture. The detection rates of crypts dilatation and branching in SSA/P and HP were 100% (25/25) and 24% (12/50, P < 0.01), 72% (18/25) and 4% (2/50, P < 0.01), respectively. Morphological features observed only in SSA/P included L-shaped crypts (48%, 12/25), pseudo infiltration of mucosa muscle (16%, 4/25), atypical nuclei (32%, 8/25), and increased mucus secretion (24%, 6/25).
CONCLUSIONSSSA/P microscopically shows prominent serration and abnormal architectures of crypts. Complete tissue sectioning and correct embedding are helpful for the diagnosis. SSA/P without cytological dysplasia should be distinguished from HP, especially those with only a few distorted crypts.

A case of Schwannoma in the submandibular gland was reported which had been misdiagnosed as pleomorphic adenoma before operation. The tumor was originated from lingual nerve which in turn invaded the Schwann membrane near the submandibular ganglion.
