Median Raphé

Median raphe cysts present anywhere between the external urethral meatus and the anus. The cysts can occur at parameatus, glans penis, penile shaft, scrotum, or perineum. Perianal region is an extremely rare location for these lesions. Here we present a 50-year-old male patient who presented with a cystic, fluctuant lesion, located at 12 o’clock in perianal region. Microscopic examination revealed a cystic lesion with keratinized and nonkeratinized stratified squamous epithelium, pseudostratified ciliated epithelium, and scattered goblet cells. The final diagnosis of the lesion was median raphe cyst. Ciliated cells and perianal localization in median raphe cysts are extremely rare characteristics.

Anal Sacs

The anal and perianal region contains multiple structure and glands, some of which are unique to the area. Anal sacs or perianal sinuses are paired, lateral, cutaneous, anal diverticula lined by a cornified, stratified squamous epithelium. Dogs have apocrine tubular anal sac glands that open into the anal sacs. Perianal glands are modified sebaceous glands, they are referred as hepatoid glands, because of their histologic resemblance to hepatocytes. Incidence,symptoms and surgical and medical management of anal tumors was studied.

Median Raphé

Background: A penile median raphe cyst is an uncommon congenital lesion that is formed due to failure of the median raphe to close completely during embryo development. The majority of the cysts are asymptomatic and often go unnoticed. Here, we report acute urinary retention as a very rare complication of a penile median raphe cyst. Case presentation: A 21-year-old single man presented with a sudden onset of acute urinary retention of one days’ duration. Urethral catheterization was done at the Emergency Department and this drained 800 ml of urine. On further questioning, he claimed that he had had a painless nodule at the glans penis since childhood. The swelling increased in size in the past week causing discomfort. He denied any history of genitalia trauma or recent sexual intercourse. On examination, there was a bluish lesion over the ventral aspect of the glans penis measuring about 3 x 2 cm. The lesion was later excised and histopathology revealed a median raphe cyst of the penis. Conclusion: A penile median raphe cyst is a rare lesion. Acute urinary retention caused by this lesion is very rare.

Objective: Localized juvenile spongiotic gingival hyperplasia (LJSGH) is a painless gingival swelling that histologically exhibits hyperplasia of the non-keratinized stratified squamous epithelium, intercellular edema and spongiosis of the spinus layer, and exocytosis of inflammatory cells. LJSGH pathogenesis remains to be elucidated, while a possible origin from the gingival sulcus epithelium is nowadays proposed. Study design: We report two cases of LJSGH with immunohistochemical evaluation of cytokeratins (CKs) 18 and 19. Results: Both cases concerned 12-year-old boys, who presented with a well-circumscribed bright red pedunculated papillary swelling on the marginal gingiva of the left maxillary lateral incisor. With the provisional diagnosis of LJSGH, the lesions were excised under local anesthesia and histological examination supported the final diagnosis of LJSGH. In both cases, the lesional epithelium showed intense and mild positivity for CK19 and CK18, respectively, while the adjacent normal gingival epithelium expressed CK19, but not CK18, only in the basal cell layer. The postoperative course was uneventful in both patients and no recurrence has been reported. Conclusion: LJSGH is a recently introduced entity that is worth attention in the clinical pediatric dentistry. Clinical and histological examination is required for the final diagnosis, while immunohistochemistry has shed light to LJSGH pathogenesis.

The stratified squamous epithelium which lines the ruminal compartment of the bovine stomach performs at least three important functions. (1) The upper keratinized layer forms a protective shield against the rough, fibrous, constantly moving ingesta. (2) It is an organ of absorption since a number of substances are absorbed directly through the epithelium. These include short chain fatty acids, potassium, sodium and chloride ions, water, and many others. (3) The cells of the deeper layers metabolize butyric acid and to a lesser extent propionic and acetic acids which are the fermentation products of rumen digestion. Because of the functional characteristics, this epithelium is important in the digestive process of ruminant species which convert large quantities of rough, fibrous feed into energy.Tissue used in this study was obtained by biopsy through a rumen fistula from clinically healthy, yearling holstein steers. The animals had been fed a typical diet of hay and grain and the ruminal papillae were fully developed. The tissue was immediately immersed in 1% osmium tetroxide buffered to a pH of 7.4 and fixed for 2 hrs. The tissue blocks were embedded in Vestapol-W, sectioned with a Porter-Blum microtome with glass knives and stained with lead hydroxide. The sections were studied with an RCA EMU 3F electron microscope.
