Subcutaneous Panniculitis-Like T-Cell Lymphoma With Hemophagocytic Lymphohistiocytosis.

Subcutaneous panniculitis-like T-cell lymphoma (SPTLP), a unique variant of primary cutaneous T-cell lymphomas, clinically mimics subcutaneous panniculitis. It is typified by the development of multiple plaques or subcutaneous erythematous nodules, predominantly on the extremities and trunk. Epidemiological findings reveal a greater incidence in females than males, affecting a wide demographic, including pediatric and adult cohorts, with a median onset age of around 30 years. Diagnosis of SPTLP is complex, hinging on skin biopsy analyses and the identification of T-cell lineage-specific immunohistochemical markers. Treatment modalities for SPTLP are varied; while corticosteroids may be beneficial initially for many patients, a substantial number require chemotherapy, especially in cases of poor response or relapse. Generally, SPTLP progresses slowly, yet approximately 20% of cases advance to hemophagocytic lymphohistiocytosis (HLH), often correlating with a negative prognosis. We report a case of a young male patient presenting with prolonged fever, multiple skin lesions accompanied by HLH, a poor clinical course, and eventual death, diagnosed postmortem with SPTLP. In addition, we also present a literature review of the current evidence of some updates related to SPTLP.

Appendiceal Diverticulitis Mimics Cecal Diverticulitis Diagnosed Preoperatively.

Appendiceal diverticulitis is an uncommon condition that clinically resembles acute appendicitis. However, it is an incidental finding in histopathological studies and is rarely diagnosed preoperatively by imaging studies. In this article, we present the clinical and imaging findings of a male patient presenting with right upper quadrant pain with a preoperative imaging diagnosis of appendiceal diverticulitis. He underwent laparoscopic appendectomy and confirmed the diagnosis of appendiceal diverticulitis. This is a rare preoperative diagnosis. The management is often like typical appendicitis which is appendectomy. It is important to differentiate it from diverticulitis of the small intestine or colon because these diseases usually require only conservative treatment.

A Review of Classification, Diagnosis, and Management of Hydrocele.

This article summarizes and updates a number of issues related to hydrocele including anatomy, embryology, classification, etiology, clinical manifestations, imaging findings, and management. Hydrocele is an abnormal collection of serous fluid between the parietal and visceral layers arising from the mesothelial lining of the tunica vaginalis that surrounds the testis and spermatic cord directly. Hydroceles result from an imbalance of secretion and reabsorption of fluid from the tunica vaginalis. Hydroceles can be divided into two types as primary and secondary. The diagnosis should be based on medical history, clinical manifestations, and imaging studies. Understanding the causes and types of hydroceles is useful for accurately diagnosing and treatment strategy. Hydroceles can be managed by conservative treatment, fluid aspiration, or hydrocelectomy.

Traumatic rupture of congenital cystic adenomatoid malformation mimicking traumatic pulmonary pseudocyst: a case report.

Thoracic trauma is commonly encountered in daily clinical practice; however, blunt thoracic trauma in patients with congenital cystic adenomatoid malformation (CCAM) is rare. CCAM rupture denotes a broad spectrum of manifestations on imaging and may be misdiagnosed as many other conditions. Consequently, this leads to inaccurate treatment and poor patient outcomes. We report the case of a girl with the initial diagnosis of a cavitary lung lesion that was likely a traumatic pulmonary pseudocyst or CCAM. The patient received medical therapy for 20 days; however, her condition did not improve. Subsequently, she underwent right lower lobectomy. Ruptured CCAM was confirmed during surgery and with histopathology. No complications occurred postoperatively, and the patient made a good recovery.

Splenic lymphangioma in adult patient treated with laparoscopic splenectomy: A rare case report.

Splenic lymphangioma is a benign cystic tumor that develops as a result of lymphatic vessels' congenital abnormalities. It is a rare condition that mostly occurs in children and young adults. Due to the lack of typical symptoms and signs, splenic lymphangioma is difficult to diagnose and often incidentally revealed during radiological examinations. We report a case of a 55-year-old Asian female, who presented with left upper quadrant abdominal pain in the past 3 days. She had mild upper abdominal tenderness, with no other specific findings. Abdominal contrast material-enhanced computed tomography revealed three hypodense lesions arising from a normal-sized spleen. The histologic findings after laparoscopic splenectomy demonstrated a 3-cm-diameter yellowish-white tumor made up of multiple cystic structures. Primary benign splenic tumors are exceedingly rare, especially in adults over 20. While small lesions are mostly asymptomatic, bigger lesions can cause organ compression or even rupture. Therefore, even in adults with pain in the left upper quadrant abdomen or enlarged spleen, splenic lymphangioma should be taken into account in the differential diagnosis. The case serves as an example of a rare congenital splenic tumor. Treatment of this benign splenic abnormality with laparoscopic splenectomy is a good, safe approach.

Review of diagnosis, differential diagnosis, and management of retroperitoneal lymphangioma.

Lymphatic malformation (LM) is the currently preferred term for what was previously known as lymphangioma. Retroperitoneal LMs are extremely rare, benign, cystic masses that arise from lymphatic vessels. They can be challenging to diagnose because they resemble other retroperitoneal cystic tumors. The development of treatment strategies for rare diseases, including retroperitoneal LM, requires the acquisition of new knowledge to enhance our understanding of the disease progression. Therefore, we present an update regarding fundamental and advanced issues associated with retroperitoneal LM. This review describes the epidemiology, histopathology, biomedicine, clinical manifestations, radiological features, differential diagnosis, and management of this lesion.

Left-sided acute appendicitis with congenital gastrointestinal malrotation.

We describe a 28-year-old man with acute appendicitis associated with gastrointestinal malrotation. The diagnosis was confirmed by a computed tomography scan, and he was treated by laparoscopic appendectomy without a Ladd procedure.

Pituitary Apoplexy and Subdural Hematoma after Caesarean Section.

Pituitary apoplexy can occur postpartum, and subdural hematoma following epidural anesthesia is a rare complication. Cooccurrence of these two complications is extremely rare and has not been previously reported in the literature. In this article, we present a case of pituitary apoplexy along with intracranial subdural hematoma happening two days after spinal anesthesia for cesarean section. The patient presented with peripheral facial nerve paralysis accompanied by headache, eye pain, and blurred vision and was diagnosed by imaging modalities. The patient made a good recovery with conservative treatment without serious health events.

Pelvic schwannoma in an adult male.

Schwannomas are benign nerve sheath tumors that are generally encapsulated and commonly detected in the head, neck, and mediastinal regions. Schwannomas localizing in the pelvis are extremely rare and tend to be asymptomatic initially due to slow growth rate. Schwannomas may be misdiagnosed as urologic or gynecologic tumors. Pelvic schwannomas are typically solitary, large, and well-circumscribed masses in the retroperitoneum or presacral areas. Other imaging characteristics are cystic degeneration, repeated hemorrhages, and calcifications. Calcification patterns can be punctate, speckled, curvilinear, or along the walls of the masses. We report a young man with a pelvic schwannoma with typical imaging features.

Traumatic Kidney in a Patient With Unilateral Renal Cystic Disease.

Renal trauma occurring in patients with unilateral renal cystic disease (URCD) is extremely rare. Unilateral renal cystic disease is benign, nonprogressive, nonfamilial, nonencapsulated, and unrelated to cysts in other organs. It should be differentiated from autosomal dominant polycystic kidney disease (ADPKD) parenthesis, multicystic dysplastic kidney disease, multiple renal simple cysts, and cystic renal neoplasms. We report a case of a 15-year-old male with URCD admitted to the hospital sustaining blunt trauma to his right flank after a motor vehicle crash. Final diagnosis in this case was renal injury in a URCD patient. The patient was treated conservatively and subsequently discharged. Unilateral renal cystic disease can be diagnosed and followed by a combination of imaging methods and functional studies. The management of URCD is conservative. Although the disease is stable, nephrectomy may occasionally be indicated when there is a strong suspicion for malignancy.

Safe endoscopic removal of ingested fish bone with esophageal perforation and impingement on the aortic wall.

Esophageal foreign bodies are common conditions that may lead to serious complications, such as esophageal perforation, neck abscess, mediastinitis, arterial injury, and lung damage. We report a rare case of esophageal fish bone impingement on the aorta that was managed without complication by endoscopic removal.

Traumatic epidural hematoma in a patient with severe schizencephaly.

Schizencephaly is a rare congenital brain structural abnormality that is not clearly understood and has no specific treatment yet. Therefore, cases related to it should be added to the literature. This report aims to introduce a rare case of severe schizencephaly co-occurring with post-traumatic intracranial epidural hematoma.

Uterine Arteriovenous Malformation: A Pictorial Review of Diagnosis and Management.

Uterine arteriovenous malformation (UAVM) is a rare condition and is classified as either congenital or acquired UAVM. Patients with UAVMs usually experience miscarriages or recurrent menorrhagia. Ultrasound is used for the initial estimation of UAVMs. Computed tomography and magnetic resonance imaging are noninvasive and valuable methods that provide good compatibility with digital subtraction angiography to support the diagnosis and treatment of UAVM. Timely diagnosis is crucial to provide appropriate treatment for alleviating complications. This article presents a pictorial and literature review of the current evidence of the diagnosis and management of UAVM.

Rasmussen's encephalitis with persistent epilepsy in a young man.

Rasmussen's encephalitis (RE) is an uncommon cause of the seizure. Important key findings of RE include intractable seizure activity in children, progressive atrophy of the involved hemisphere, and small hemisphere with the large ventricle.

Diffuse Gallbladder Adenomyomatosis with an Inflammatory Complication in an Adult.

Gallbladder adenomyomatosis (GA) is a benign alteration of the gallbladder wall. There are three types involved: segmental, fundal, and diffuse pattern; the last type is very rare. Ultrasound is the imaging method of choice for diagnosing that shows Rokitansky-Aschoff sinuses with cholesterol deposition creating comet-tail artifacts. Asymptomatic GA does not require surgery in case there are no malignant lesions defined by imaging diagnosis. We present the rare case of a 51-year-old man who was admitted to hospital due to abdominal pain concomitant with inflammatory syndrome. Imaging and histological findings were appropriate to diagnose diffuse GA and complication of cholecystitis.

Balo's Concentric Sclerosis Mimicking Tumor on Magnetic Resonance Imaging in a Young Patient.

Balo's concentric sclerosis (BCS) is a rare demyelinating disease known as Multiple Sclerosis (MS) lesion type III. It is a disease of the white matter of the brain characterized by a round lesion with variable concentric myelinated and demyelinated layers, appearing as "onion bulb." We present a case of BCS and discuss the imaging findings and management strategies of this disease. A 26-y-old male developed headache, weakness, and numbness of limbs. Magnetic resonance imaging (MRI) showed concentric lamellar like demyelinating lesions at the subcortical regions. The patient's neurological symptoms were consistent with the MRI findings.
