Port-wine stain is a type of common congenital superficial telangiectasia in the dermal layer mostly occurring on the forehead, face, and neck. The affected skin shows abnormal red or purple lesions, which darken and thicken. Nodular changes may develop with advancing age. If untreated, port-wine stains scarcely regress, which can have serious lifelong psychological impact on patients and affec...

The Ziehl–Neelsen (ZN) stain, also known as the acidfast stain, has been reported to be helpful in detection and identification of Schistosoma eggs. In histological sections, Schistosoma mansoni egg shells appear as ZN positive and Schistosoma haematobium shells as ZN negative. The staining target of the responsible ZN component (carbolfuchsin) in the shell is unknown. Because carbolfuchsin is ...

A unique Monte Carlo program capable of accommodating an arbitrarily complex geometry was used to determine the energy deposition in a true port wine stain anatomy. Serial histologic sections taken from a biopsy of a dark red, laser therapy resistant stain were digitized and used to create the program input for simulation at wavelengths of 532 and 585 nm. At both wavelengths, the greatest energ...

A 57-year-old male was found to have papillary transitional cell carcinoma of the urinary bladder and underwent a tranurethral resection of the tumor. He suffered from multiple asymptomatic red papules on glans penis after 9 th intravesical therapy with Bacillus Calmette-Guerin (BCG ). His left inguinal lymph node was enlarged and tender. The skin lesions were found to be due to suppurative gra...

The light microscopic structure and the effect of superior cervical ganglionectomy on the pineal gland of Rhesus monkey was studied in 24 animals. The animals were divided into three groups. Group I normal controls, Group II after unilateral and Group III after bilateral ganglionectomy. The animals in group II were sacrificed 15 days and group III were sacrificed 21 days after the operation. Ev...

It is not uncommon to receive hemorrhagic fluids for cytological examination. The red blood cells impair diagnostic efficacy of smears. The body fluid can be processed in many waysNSRT (Normal saline rehydration technique) is one such technique. The present study was done to evaluate quality of smears prepared by NSRT and Carnoy’s fixation. The smears were stained by Hematoxylin & Eosin and Lei...

Fig. 1. (A) Peripheral blood shows neutrophils with toxic granules and two intra-cytoplasmic yeast forms of Histoplasma capsulatum in the cell on the left (May-Grunwald Giemsa, ×1,000). Inset: The fungus was brightly positive for periodic acid–Schiff stain (hematoxylin counterstain, ×1,000). (B) Hemodilute bone marrow smears showed dysgranulopoiesis with 5% blasts (May-Grunwald Giemsa, ×1,000)....
