1. McCune-Albright syndrome - A case report with transmission electron microscopy
Abstract McCune - Albright syndrome is a genetic disease with cutaneous mosaicism caused by post-zygotic activating mutations in GNAS locus, it has a triad of fibrous bone dysplasia, café-au-lait macules and precocious puberty. We examined a 22-year-old female patient with café au lait spot in right side of the abdomen, with a chessboard - like distributio

2. Dacriocistocele congênita: relato de caso e conduta
A dacriocistocele representa uma rara anomalia congênita da região medial da órbita, causada pela obstrução distal (ao nível da válvula de Hasner) e proximal (ao nível da válvula de Rosenmüller) da via lacrimal, com subsequente dilatação do saco lacrimal. Recebe o nome de mucocele, quando seu conteúdo representa muco, ou amniocele, quando o seu

3. Cisto epidérmico pré-sacral no adulto
Presacral tumors are relatively uncommon. We report a case of presacral epidermal cyst in a 29-years-old female, which was completely extirpated through a posterior approach ,whitout removal of the coccyx. Histological examination showed a cyst lined by keratinized stratified squamous epithelium.

4. Recurrent epidermal cyst infection caused by Brucella melitensis in a diabetic patient.
A presternal swelling diagnosed clinically as a sebaceous cyst in a 60-year-old diabetic patient was surgically drained, and the aspirated purulant material yielded growth of Brucella melitensis. The swelling recurred four times and was drained on every occasion. The patient responded to surgical excision and antibrucella treatment. The histologic diagnosis

5. Epidermal growth factor receptor activity mediates renal cyst formation in polycystic kidney disease.
A consistent phenotype observed in both human patients and several different mouse models of autosomal recessive polycystic kidney disease (ARPKD) is an increased activity of the epidermal growth factor receptor (EGFR) in the affected kidneys. To determine whether this increased activity of the EGFR is a functional event that is directly part of the disease

6. Adenocarcinoma arising within a tailgut cyst: clinicopathological description and follow up of an unusual case.
Full clinicopathological details and clinical follow up of a case of malignant transformation within a tailgut cyst are presented. A 43 year old woman presented with signs and symptoms of an imminent threatened abortion. Routine examination identified a coincidental, asymptomatic retrorectal/presacral mass. Following imaging studies, surgical resection was c

7. Immunocytochemical expression of growth factors by odontogenic jaw cysts.
AIM: To determine the immunocytochemical pattern of expression of transforming growth factor (TGF) alpha, epidermal growth factor (EGF), and TGF beta in the three most common types of odontogenic jaw cyst. METHODS: Growth factor expression was detected in paraffin wax sections of odontogenic cysts (27 odontogenic keratocysts, 10 dentigerous cysts, and 10 rad

8. Ocular findings in linear sebaceous naevus syndrome.
The case of a 5-month-old black female child with a linear sebaceous naevus syndrome and multiple congenital anomalies is presented. Ocular malformations consisted of colobomatous changes of the lid and retina, dermoid of the conjunctiva, chorioretinal changes, and peripapillary atrophy of the optic nerve. Systemic findings included midline cleft of the seco

9. Kidney-specific inactivation of the KIF3A subunit of kinesin-II inhibits renal ciliogenesis and produces polycystic kidney disease
Polycystic kidney disease (PKD) is the most common genetic cause of renal failure in humans. Several proteins that are encoded by genes associated with PKD have recently been identified in primary cilia in renal tubular epithelia. These findings have suggested that abnormalities in cilia formation and function may play a role in the pathogenesis of PKD. To d

10. Production of bone-resorbing activity and colony-stimulating activity in vivo and in vitro by a human squamous cell carcinoma associated with hypercalcemia and leukocytosis.
A squamous cell carcinoma of 33-yr-old patient who developed marked leukocytosis and hypercalcemia was transplanted into nude mice in which more marked leukocytosis and hypercalcemia also developed. This tumor (LJC-1-JCK) produced a colony-stimulating factor (CSF) and formed a cyst in the tumor from which a CSF-producing cell line (T3M-1) was established. Th

11. Effectiveness of positron emission tomography for the detection of melanoma metastases.
OBJECTIVE: The purpose of this study was to determine the sensitivity, specificity, and clinical utility of 18F 2-fluoro-2-deoxy-D-glucose (FDG) total-body positron emission tomography (PET) scanning for the detection of metastases in patients with malignant melanoma. SUMMARY BACKGROUND DATA: Recent preliminary reports suggest that PET using FDG may be more
