Amniotic band sequence (ABS) is an uncommon and heterogeneous congenital disorder caused by entrapment of fetal parts by fibrous amniotic bands, causing distinctive structural abnormalities involving ...limbs, trunk, and craniofacial regions. The incidence ranges between 1/1200 and 1/15,000 live births, but is higher in stillbirths and previable fetuses. The intrinsic theory attributes the constriction band syndrome as an inherent development defect of embryogenesis while the extrinsic theory proposes that an early amnion rupture is responsible for the adherent bands. It is also suggested that amputations and constriction rings might be due to vascular disturbances. Anomalies resulting from amniotic bands are quite variable and sometimes may simulate chromosomal abnormalities. The authors report a case of a 36-week-gestation male neonate who lived for 29 hours after a vaginal delivery with an Apgar score of 8/9/9. The mother was primipara, and the prenatal was uneventful except for two episodes of urinary tract infections. The newborn examination depicted multiple anomalies characterized by exencephaly, bilateral labial cleft with distorted nostrils and palate cleft. There was also facial skin tag band, exophthalmos with hypoplasia of the eyelids. The limbs showed distal amputation of the fingers in both hands and feet, oligodactyly associated with syndactyly in the left foot, ring constriction in the right leg, the presence of right hyperextension, and clubfoot. The upper limbs showed length discrepancies. Karyotype analysis was normal at 46 XY. The authors conclude that the recognition of the malformations secondary to ABS is important in genetic counseling to prevent misdiagnosis between chromosomal and secondary disruption disorders.

The diffuse leprosy of Lucio and Alvarado is considered the most anergic spectrum of leprosy and is characterized by a generalized skin infiltration, with a diffuse and total alopecia associated with ...a systemic involvement. When the number of bacilli in the endothelium is high a medium and small vessel’s leukocytoclastic vasculitis develop over a diffuse and generalized cutaneous involvement by leprosy, what leads to large necrotic and ulcerative lesions, named after Lucio’s phenomenon. We present an autopsy case of a female patient who has been presenting ulcerated lesions for the last 20 years without a specific diagnosis. Three weeks before the patient’s admission the lesions got worse and new ones appeared. Due to the extension of cutaneous involvement and consequent infectious complications the patient evolved to a fatal outcome. The pathological evaluation revealed systemic involvement by leprosy and multiple skin ulceration. The cutaneous lesions were due to leukocitoclastic vasculitis and vascular occlusion, compatible with Lucio’s phenomenon .
Hypoplastic left heart syndrome (HLHS) is a congenital heart disease, which, despite the current improved knowledge about its management and surgical treatment, is still associated with high ...mortality, especially in the early neonatal period and before the second stage of reconstruction surgery. The low rate of prenatal diagnosis and delayed diagnostic suspicion results in unsuccessful therapeutic intervention, even though the real impact of early diagnosis and intervention on mortality and quality of life of patients is still uncertain. Fortunately, this syndrome of challenging treatment is not that frequent. It involves a spectrum of obstructions to the blood flow within the left heart and is characterized by an inappropriate size of the left ventricle associated with a wide variety of valvular dysfunctions. Treatment ranges from heart transplantation to palliative surgical procedures. The authors describe a case of a newborn with HLHS, whose diagnosis was made after birth because of early respiratory failure. Despite the use of prostaglandin the newborn died. An autopsy was performed and the anatomical findings were described.
Schistosomiasis is one of the most common parasitic diseases, still considered of public health significance. Acute schistosomiasis is of difficult diagnosis and therefore has been overlooked, ...misdiagnosed, underestimated and underreported in endemic areas. The delay between the exposure to contaminated water and the initial symptoms may explain this challenging diagnosis. Acute schistosomiasis is frequently reported in non-immune individuals while reinfection cases occurring in endemic areas is scarcely documented. The later usually shows a benign course but fatal cases do exist. The authors report a case of a young female patient, in the late puerperium, with a three-month history of weight loss, intermittent fever, cough, thoracic and abdominal pain and increased abdominal girth. Physical examination showed a tachycardia, tachypnea and hypotension. Laboratory tests showed a mild anemia, eosinophilia, and a slightly elevation of liver enzymes. Thorax and abdominal multidetector computed tomography evidenced a diffuse and bilateral pulmonary micronodules and peritoneal and intestinal wall thickening. The patient progressed rapidly to hepatic insufficiency, and death after respiratory insufficiency. An autopsy was performed and the findings were compatible with acute Schistosomiasis in a patient previously exposed to

Acute erythroid leukemia (AEL) is a rare subtype of acute myeloid leukemia (AML), characterized by predominant erythroid proliferation. The 2008 World Health Organization (WHO) classification of AML ...defined two AEL subtypes: erythroleukaemia (EL), in which erythroid precursors account for 50% or more of all nucleated bone marrow cells and myeloblasts account for 20% or more of the nonerythroid cell population; and pure erythroid leukemia (PEL), in which erythroid precursors account for 80% or more of all nucleated bone marrow cells. We report the case of an elderly female patient with wasting syndrome and pancytopenia without evidence of blasts in peripheral blood. A diagnosis of PEL was established on the basis of bone marrow biopsy findings. The patient died on postadmission day 20, and an autopsy was performed. We reclassified the disease as EL on the basis of the autopsy findings, which included myeloblasts accounting for more than 20% of the nonerythroid cells in the bone marrow, as well as leukemic infiltration and myeloid metaplasia in solid organs, such as the liver, spleen, kidneys, adrenal glands, and abdominal lymph nodes. A rare disease, AEL accounts for less than 5% of all AMLs and is practically a diagnosis of exclusion. Autopsy reports of AEL are extremely rare in the literature. We demonstrate that in the case reported here, leukemia cells tended to infiltrate solid organs with myeloid metaplasia. Our findings also show that a larger neoplastic bone marrow sample is crucial to the correct diagnosis of EL, which is based on morphological and quantitative criteria.
