Necrotizing lymphadenitis in systemic lupus erythematosus: is it Kikuchi-Fujimoto disease?

Kikuchi-Fujimoto disease (KFD; also called Kikuchi disease) is a rare disorder clinically characterized by lymphadenopathy along with constitutional symptoms and several systemic features which may closely mimic infections, malignancies, and autoimmune diseases. Systemic lupus erythematosus (SLE) is an autoimmune disorder which may have several clinical manifestations similar to KFD. Association of KFD with SLE is only rarely described, and whether this is a chance incidence or Kikuchi disease is a localized manifestation of SLE per se remains a matter of debate. We report here coexistence of these two diseases in 1 patient.

Meckel-Gruber syndrome: Report of two cases

Meckel-Gruber syndrome (MKS) is an autosomal recessive disorder, characterized by a combination of renal cysts and variably associated with features including developmental anomalies of the central nervous system (typically encephalocele), hepatic ductal dysplasia, cysts, and polydactyly. It is a rare syndrome with highest incidence in Gujarati Indians and Finnish population. We report two such cases of MKS in non-Gujarati Indian which were diagnosed by neonatal autopsy.

Congenital cystic adenomatoid malformation of lung: Report of two cases with review of literature.

Congenital cystic adenomatoid malformations (CCAM) also known as congenital pulmonary airway malformation is a developmental, non-hereditary, hamartomatous abnormality of lung with unknown etiology. It is a rare disease with an incidence of 1 in 25,000 to 1 in 35,000. It is a disease of infancy with most of the cases diagnosed within first 2 years of life. We report autopsy findings of two fetuses with congenital cystic adenomatoid malformation (Stocker Type II and I) with brief review of literature.

Glomerulogenesis: can it predict the gestational age? A study of 176 fetuses.

BACKGROUND Accurate assessment of gestational age of fetuses is essential from both clinical and medico-legal point of view. Crown-rump length, crown-heel length, foot length, and the weight of the fetus are the commonly used parameters for fetal age assessment. However, this estimate often lacks accuracy and sometimes is necessary to combine other data. An analysis of the embryological development of nephrons in the kidney can assist in this determination. OBJECTIVE To correlate the gestational age with the histological study of sequential development of nephrons in fetal kidney. MATERIALS AND METHODS This study included 176 fetuses delivered between June 2009 and June 2011 and aged from 12 to 40 weeks. The number of glomerular generations counted in hematoxylin and eosin-stained microscopic sections of the kidneys were correlated with the reported period of gestation based on obstetrical methods. Regression analysis was used to determine the statistical significance of the correlation. RESULTS A high degree of statistically significant correlation was observed between the period of gestation and the number of glomerular generations (P value < 0.0001). CONCLUSION The histological assessment of the number of glomerular generations in kidney can be used as a reliable method of estimating fetal age.

Sirenomelia with associated systemic anomalies: an autopsy pathologic illustration of a series of four cases.

Sirenomelia, a developmental defect involving the caudal region of the body, is associated with several internal visceral anomalies. We report a detailed spectrum of anomalies in an autopsy study of four fetuses with sirenomelia (gestational ages - 20, 21, 22.4, and 22.5 weeks). Three of the fetuses had single umbilical artery, with genitourinary and gastrointestinal anomalies. Central nervous system anomalies were evident in two of the fetuses, with alobar holoprosencephaly in one and lumbar meningomyelocele in another. The most common gastrointestinal anomaly was blind ended gut (imperforate anus), while esophageal atresia and omphalocele were noted in one case each. Renal hypoplasia was seen in two fetuses, renal agenesis in one and cystic renal dysplasia was noted in one case. Literature regarding pathogenesis of this condition is briefly discussed.

Limb body wall complex: A rare anomaly

We present autopsy findings of a case of limb body wall complex (LBWC). The fetus had encephalocele, genitourinary agenesis, skeletal anomalies and body wall defects. The rare finding in our case is the occurrence of both cranial and urogenital anomalies. The presence of complex anomalies in this fetus, supports embryonal dysplasia theory of pathogenesis for LBWC.

Primary cutaneous leiomyosarcoma: A rare malignant neoplasm

Primary cutaneous leiomyosarcoma (PCL) is an exceedingly uncommon malignant superficial soft tissue sarcoma with a predilection for middle-aged to elderly male. Morphologic differential diagnosis includes a host of other malignant spindle cell neoplasms, thereby necessitating the use of a panel of immunohistochemical markers to arrive at a definitive diagnosis. We report a case of PCL arising in the right leg of a 70-year-old male.

Anencephaly: A pathological study of 41 cases

Background : Anencephaly is a lethal neural tube defect which is due to the defective closure of rostral pore of neural tube. In more than 50% of cases it is associated with other systemic anomalies. Hence this study was undertaken to assess pathological parameters associated with anencephaly in particular attention to associated systemic anomalies. Materials and Methods: It is a study on 41 anencephaly fetuses conducted in the Department of Pathology. The period of study is from January 2001 to December 2011. Results: Out of 41 cases, 30 (73%) cases showed presence of systemic anomalies, 48.5% of the cases were observed in primigravida. Most common associated anomaly was spina bifida followed by gastrointestinal anomalies. Conclusion: Pathological examination of the abortus is essential to document the associated anomalies.

Primary endobronchial Hodgkin's disease.

We report a case of primary pulmonary Hodgkins disease presenting as an endobronchial mass. Tissue diagnosis was made by microscopic examination following open thoracotomy and excision biopsy of the mass. The patient responded well to the chemotherapy regimen.

Polycystic horseshoe kidney.

Polycystic kidney disease (PKD) is a hereditary disorder of autosomal dominant or recessive inheritance. Horseshoe kidney is a common renal fusion anomaly during embryogenesis. Combination of both PKD and horseshoe kidney is rare, with an incidence of one in 1,34,000–8,00,000 live births.1 Less than twenty cases have been reported till date in adults and only one in the fetus.2,3 We report the autopsy findings of this rare anomaly in a fetus with brief review of literature.
