Primary aortic sarcoma is a rare and aggressive malignancy with only approximately 190 cases reported in the literature. While angiosarcoma and intimal sarcomas represent an estimated 67.7% of malignant aortic tumours, spindle cell sarcomas are even more exclusive, consisting of only 0.9% of malignant aortic tumours. Differentiated from other malignant aortic tumours, spindle cell sarcomas are of mesenchymal origin and usually express vimentin and osteopontin. Clinical presentations are variable and nonspecific, ranging from back pain, abdominal pain or elevated blood pressure, misleading to differentials like pulmonary emboli or aortic aneurysms such as in our case here. In this article, we discuss the finding of an extremely rare aortic sarcoma masquerading as a pulmonary embolism. The patient underwent surgical resection; however, the course was complicated by the development of brain metastases and intracranial haemorrhage. The literature is expanding regarding the evolution of adjuvant chemotherapy and ralignant aortic tumours have a poor prognosis, and of the various types of malignant aortic tumours, aortic sarcomas have a particularly poor prognosis with a 5-year survival rate of 8%.The exact pathophysiology of these malignancies is unknown but is thought to be related to the MDM2-p53 pathway and may be related to Li-Fraumeni syndrome.
Malignant aortic tumours are rare and can present with a multitude of symptoms ranging from constitutional symptoms to abdominal discomfort to unexplained hypertension. Spindle cell sarcomas represent 1 of the least common malignant aortic tumours reported in the literature.Malignant aortic tumours have a poor prognosis, and of the various types of malignant aortic tumours, aortic sarcomas have a particularly poor prognosis with a 5-year survival rate of 8%.The exact pathophysiology of these malignancies is unknown but is thought to be related to the MDM2-p53 pathway and may be related to Li-Fraumeni syndrome.An 81-year-old patient presented to the emergency department with a dark lesion on his forehead and swelling of his left eye, 3 days after a minor forehead injury and skin laceration. He also showed singular papules on his chin, upper chest, upper arms and back, later evolving into vesicles. Polymerase-chain reaction testing of vesicle content was positive for VZV and HSV-1, confirming a diagnosis of disseminated cutaneous herpes virus infection and concomitant HSV-1 reactivation. buy BGB-16673 Antiviral and antibiotic treatment was initiated for 1 week with an immediate response. This case report highlights the association of head trauma and subsequent reactivation of VZV in patients at risk. Simultaneous reactivation of HSV-1 and VZV is rare in immunocompetent patients.
Minor trauma can cause VZV and HSV reactivation.Consider herpes virus reactivation in case of unclear rash; the appearance of vesicles can be delayed for a few days.Screen for immunodeficiency disorders in disseminated herpes virus infection; if non-apparent, close monitoring is recommended.

Aetiologic screening showed PVB19 primary infection and concomitant SLE flare-up. We discuss the causative interactions between PVB19 and SLE in the pathogenesis of the disease. Difficulty diagnosing inaugural SLE flare-up concomitant with PVB19 infection can lead to delayed diagnosis and treatment. Inversely, overtreating a SLE-mimicking PVB19 infection with immunosuppressive agents can be highly detrimental.
The differential diagnosis between parvovirus B19 primary infection and systemic lupus erythematosus flare-up can be difficult.Parvovirus B19 primary infection can elicit authentic severe systemic lupus erythematosus flare-up that requires urgent immunosuppressive therapy.Parvovirus B19 primary infection can also mimic systemic lupus erythematosus.

Variegate porphyria (VP) is a rare disorder of haem biosynthesis. We report a novel association with hepatitis A infection.

A 31-year-old man was diagnosed with acute hepatitis A infection. During recovery, he presented with abdominal pain and a photoaggravated blistering skin eruption.

Urine porphyrin precursors were markedly raised with high coproporphyrin III isomer levels. Faecal protoporphyrin levels were markedly increased and a maximum plasma fluorescence emission at 629 nm was noted.

Acute hepatitis A infection, and the associated metabolic stress exerted on the haem biosynthetic pathway, induced overt presentation of latent VP.

There should be a high index of suspicion for an acute cutaneous porphyria when a photosensitive rash is accompanied by neurovisceral symptoms.Latent porphyria may be overtly manifested after appropriate triggers which stress the metabolic haem biosynthetic pathway. One such trigger demonstrated by this case presentation is acute hepatitis A infection.The diagnostic er specialist analysis with fractionation of urinary and faecal porphyrins is necessary to distinguish between the two different acute cutaneous porphyrias.Inferior vena cava syndrome is rare and often difficult to diagnose because of its rarity and consequent low suspicion. We describe the case of a 28-year-old female patient with a history of nephroblastoma of the right kidney, stage IV, with a favourable histology with epidural metastasis (D5-D9), diagnosed at 3 years of age. The patient underwent treatment with surgery, chemotherapy and radiotherapy. The patient suffered from sudden low back pain worsening over 2 weeks, with progressive inability to walk. The pain radiated to the front of the thighs. Concomitantly, oedema of the lower limbs with cephalocaudal progression was observed. At admission to our institution, the physical examination showed peripheral oedema, abdominal wall venous collaterals, an inability to walk due to low back pain in the supine position, with no neurological deficits. Lumbar MRI showed exuberant epidural venous congestion. The hypothesis of inferior vena cava thrombosis (IVCT) was considered and confirmed by angio-CT. IVCT is prevalent in patients with congenital anomalies of the inferior vena cava, occurring in approximately 60-80% of these cases, and most published series on inferior vena cava syndrome refer to thrombotic complications in this subgroup of patients.
