Triphallia: the first cadaveric description of internal penile triplication: a case report.

Introduction: Triphallia, a rare congenital anomaly describing the presence of three distinct penile shafts, has been reported only once in the literature. This case report, based on an extensive literature review, describes the serendipitous discovery during cadaveric dissection of the second reported human case of triphallia, distinctly morphologically different from the previous case.

Case Presentation: Despite the normal appearance of external genitalia on examination, the dissection of a 78-year-old white male revealed a remarkable anatomical variation: two small supernumerary penises stacked in a sagittal orientation posteroinferiorly to the primary penis.

A Cadaveric Case of Bilateral Adrenal Hyperplasia With Lung Cancer: A Paraneoplastic Syndrome?

Bilateral adrenal hyperplasia associated with primary lung cancer may arise from either an adrenocorticotropic hormone (ACTH)-dependent paraneoplastic syndrome or metastatic hyperplasia. Ectopic Cushing's syndrome manifests as a paraneoplastic syndrome characterized by the secretion of ACTH from malignant cells. This secretion can in turn overstimulate the adrenal cortex, resulting in adrenal cortical hyperplasia followed by hypercortisolism.

Study of endometrial thickness by ultrasonography in regular and irregular menstrual cycles.

Endometrium is the mucosal layer of uterus. Throughout the reproductive age endometrium undergoes cyclical changes during each lunar month to prepare the uterus for implantation. Endometrium proliferates and regenerates during menstrual cycle.

Pyramid heart: uncommon sequel of a common disease.

A 40-year-old woman presented 19 years after ring-annuloplastyfor rheumatic mitral regurgitation. Long-standing rheumatic heartdisease resulted in an unusual finding on her chest radiograph.

The Thebesian valve: Gatekeeper to the coronary sinus.

Clinical cardiac procedures such as electrophysiology studies, catheter ablation of arrhythmias, retrograde cardioplegia delivery, cardiac resynchronization therapy and, more recently, percutaneous mitral annuloplasty, involve cannulation of the coronary sinus (CS). The presence of a membrane closing the orifice of the CS may cause difficulties during these interventions. Thus, detailed knowledge of the variations and anomalies of the valve of the CS, or the Thebesian valve, now has practical significance.
