Tumour
bilateral 1-3 of cases, synchronous or metachronous, similar or dissimilar types. Commonest is seminoma or spermatocytic seminoma but beware lymphoma in the older age group. testicular cancer usually presents with a painless lump or swelling of some duration. Investigation involves careful clinical examination and ultrasound assessment to detect hypoechoic areas of tumour. Tumour staging is by chest X-ray for pulmonary involvement and CT scan for abdominopelvic and mediastinal lymph node...
Small cell carcinoma
Small round fusiform nuclei (x2-3 lymphocyte size) with granular chromatin, moulding and an inconspicuous nucleolus, DNA crush and vessel artefact (Azzopardi effect), fir tree hyaline stroma, apoptosis, necrosis and mitoses. The nuclear features are the diagnostic characteristic of small cell carcinoma. Note that there can be a scattered population of large bizarre (polyploid) cells. intermediate larger nucleus more cytoplasm and most likely represents better preserved fixed oat...

Extent Of Local Tumour Spread
Lymphocytic reaction prominent sparse. Lymphocytic reaction is a consistent (80 ) feature of seminoma, and granulomas can also be present in up to 50 of cases. Sometimes the inflammatory infiltrate can be so intense that it partially obscures the germ cells and immunohistochemical markers are necessary. The intensity of inflammation and presence of granulomas are not prognostically significant. ITGCN carcinoma in situ sample the adjacent testis. Intratubular spread...
Comments On Adrenal Gland
Metastatic carcinoma in the adrenal gland, particularly from lung, breast and kidney, is commoner than a primary neoplasm and usually detected by follow-up CT scan. Sometimes CT-guided needle core biopsy or FNA is used to make this distinction and more often primary adrenal neoplasms present either as a symptomatic or incidental mass or are characterized by their endo-crinological symptoms and signs and resultant biochemical profiles. Phaeochromocytoma is a contraindication to biopsy due to the...

It may also present with prostatism but is frequently detected because of an elevated serum PSA with digital rectal examination (DRE) either as part of a screening programme...
Gastric Carcinoma
gastric cancer can present with anaemia, weight loss or dyspeptic symptoms. Investigation is by endoscopy with biopsy. Staging for local and distant disease includes ELUS endoluminal ultrasound tumour depth and nodal spread , CT scan chest, abdomen and pelvis, PET scan and peritoneal laparoscopy with cytological washings and biopsy. Non-regional disease is an indicator for palliative treatment including chemotherapy, and surgery if there is anatomical dysfunction, e.g. extensive ulceration and...

Chest X-ray can detect concurrent lung cancer. Extent of resection...
