Granulocytic sarcoma (GS) or chloroma is a neoplasia of immature myeloid cells. Bones, skins, soft tissues and lymph nodes are the most frequently involved organs with this entity and not infrequently it is diagnosed histopathologically as non-Hodgkin's lymphoma (NHL). Ovarian granulocytic sarcoma is a rare entity in daily practice. Here we report an ovarian granulocytic sarcoma, initially diagnosed as NHL, and review the literature.
Introduction: Idiopathic intracranial hypertension (IIH) is a rare clinical condition in which an increase in intracranial pressure is seen without a lesion in the head. The association of IIH with haematological malignencies is not well known. Case: We present 19-year-old male with frequent episodes of headache that lasted up to 24 hours, localized to the bilateral temporal region accompanied with nausea and vomiting for two months. On the neurological exam, the lateral gaze was slightly restricted. Ophthalmological exam revealed bilateral papilledema, which was more pronounced on the right. Bilateral concentric constriction, more pronounced on the right , was observed on the computerized visual field exam. Brain Magnetic Resonance Imaging (MRI) showed swelling in the optic nerve sheats, rather than on the right. In the analysis of cerebrospinal fluid (CSF), the opening pressure was 370 mmH2 Cytological examination of the CSF showed atypical lymphoid cells. The patient was diagnosed as precursor lymphoblastic leukemia/lymphoma. Conclusion: Acute leukemia–induced clinical IIH has not been reported in the literature up to now, and the present case study will contribute to the literature in this regard. This phenomenon will be noteworthy for clinicians who encounter high CSF opening pressure, abnormal CSF biochemistry, and substantial cytology in cases presenting with clinical IIH.
Objective:We aimed to document the reasons of perinatal deaths in a large autopsy series performed in our institute, which is a reference center in the Çukurova region of Turkey. Material and Method:The study included 2150 autopsies performed between January 2000 and December 2012at our institute.Diagnoses were categorized according to the detected pathologies; congenital malformations were detailed based on systems. Results:A pathology was detected in 1619 of 2150 (73.3%) autopsies.Congenital malformations were the most common diagnosis with 68.2%.Neural tube defects and central nervous system malformations were the most frequent system malformation in 28.8% of cases, followed by the urogenital system (11.4%) and musculoskeletal system (8.3%),respectively.Malformation syndromes including multisystem anomalies were defined in 109 cases (9.3%). Conclusion:Congenital malformations are the most common reason for perinatal deaths, with autopsy having an additive role to prenatal and genetic evaluations and providing foresight for planning a subsequent pregnancy.
The diagnosis of cutaneous leishmaniasis (CL) may depend on the detection of the parasite in histologic sections, the growth of the promastigotes in culture, or the identification of parasite by other techniques. We performed polymerase chain reaction (PCR) on paraffin-embedded biopsies to determine the validity of this technique for diagnosis of CL. PCR was used to detect the parasite using 2 different DNA extraction methods. PCR was positive in all 20 cases when the Leishmania parasite was detected by light microscopy. Twenty-seven of 34 cases that were negative microscopically for the parasite were positive using PCR. The first extraction method of DNA identified leishmanial DNA in 41 of 54 cases (75.9%); the second extraction of DNA was positive in 47 of 54 cases (87%). PCR was negative in all of the nonleishmaniasis cases. The PCR-based method appears to be a useful diagnostic approach for identification of suspected cases of CL.
There is an ongoing debate whether to perform orchiectomy or orchidopexy following testicular torsion (TT) in cases where the testis seems non-viable. The main problem is lack of objective criteria defining testicular viability. The aim of this study was to investigate the grade of injury in orchiectomy specimens obtained from cases of TT and its association with clinical findings.This multicenter retrospective study involved double-blinded reassessment of the patient files and the pathological specimens using Mikuz classification to analyze the relation between clinical and pathological findings.A total of 289 patient charts from 14 centers were reviewed and 228 were included in this study. Twenty (8.8%) patients had grade 1 injury which refers to reversible injury. The clinical findings of these 20 patients were compared to 208 patients with higher grades of injury. As expected, there was statistically significant difference regarding duration of symptoms (p < 0.001); however, range was wide in both groups (as long as 96 h for grade 1 and as short as 7 h for higher grades). There was no statistically significant difference in any other variable including age (median 14 for both, p = 0.531), symptoms (pain: 19/20 vs. 189/202, p = 0.801; swelling: 13/19 vs. 168/197, p = 0.094), absence of blood flow in Doppler US (15/19 vs. 164/197, p = 0.635), or degree of torsion (median 720° for both, p = 0.172).Our study revealed necessity for better criteria to define viability of testis following TT. Histopathological injury appeared to be reversible even in some patients with more severe perioperative findings, late admission, or high degree of twisting. Our findings support the tendency for testicular fixation instead of orchiectomy as none of the clinical or perioperative findings could be attributed to high-grade injury.
