OBJECTIVETo analyze the clinical character, diagnosis and treatment of badly necrotic pyogenic infection in cervical part with pneumatosis of vomica.

METHODSThe clinical character, diagnosis and treatment of badly necrotic pyogenic infection in cervical part with pneumatosis of vomica of 46 cases were investigated retrospectively.

RESULTSLateral and bilateral neck infection cases were 38 and 8 respectively. 30 cases formed primary pyogenic infection in cervical part with pneumatosis of vomica, and 16 did from adjacent sites. Besides the characters of the acute infection, gas storage in deep cervical part abscess was notable. CT and B Ultrasonic examination provided useful informations such as sizes, shapes, capacity, extents of abscess and the relationship between the abscess and vessel or vital organ. Diagnosis puncture and germiculture were performed before and after operation. The results showed that 25 of 46 cases were infected by staphylococcus or streptococcus, and 21 cases did by other bacterium. Exploration and drainage treatments were performed. All cases were cured except 2 died.

CONCLUSIONDiagnostic puncture, CT and/or B Ultrasonic examination are essential for diagnosis and presurgical planning. Germiculture provides reliable evidence for finding pathogeny and therapy. The most possibilities of pyogenic infection with pneumatosis of vomica in cervical part are the action of aerogenic bacterium, infection both in cervical part and chest or swallowing movement of pharynx.

The diagnosis of cystic liver disease has made great progress with the advent of enhanced imaging techniques. At the same time, its management has gradually improved over the past few decades, providing the basis for the development of appropriate diagnostic and treatment guidelines. To this end, the European Association for the Study of the Liver has developed clinical guidelines for the diagnosis and treatment of non-infectious cystic liver disease. This guideline put forward recommendations based on an in-depth review of the relevant literature for addressing clinical issues, including the diagnosis and treament of hepatic cysts, hepatic mucocystic tumors, biliary hamartomas, polycystic liver disease, Caroli disease or Caroli syndrome, biliary hamartomas, and peribiliary cyst.

To describe the first case of the treatment of a corneoscleral cyst by distilled water injection into a corneal cyst. The anterior wall of a cyst of the limbal communication was punctured with a surgical blade. Aspiration and irrigation of the contents of the cyst with a 27-gauge anterior chamber cannula were performed repeatedly, three times. Distilled water, instead of balanced salt solution, was injected into the collapsed cyst, and was then aspirated completely after 5 minutes. The injection and aspiration of distilled water was repeated once more. The scleral cyst was surgically excised. Twelve months after surgery, several small white granular opacities, presumably epithelial cell nests, were observed on the interface of the collapsed cyst cavity, but there was no recurrence of the cyst. The best spectacle-corrected visual acuity (BSCVA) was 1.0 with a correction of +1.25-2.00 X 45. No significant change in central corneal endothelial cell density was noted. We suggest that this simple technique may represent an alternative method for the management of corneal cysts, and may have less risk of developing a corneal opacity or causing other serious damage to surrounding tissues.

INTRODUCTIONThis report describes a "parasitic" endometriotic cyst of the small bowel.

CLINICAL PICTUREA menopausal woman with a pelvic mass presenting years after commencing hormone therapy.

TREATMENTWe performed laparoscopic excision of a cystic tumour attached to the small bowel with a solitary vascular pedicle.

OUTCOMEHistology confirmed it to be an endometriotic cyst of ovarian origin, probably resulting from spillage during previous surgery and reactivation with hormone therapy.

CONCLUSIONSWe discuss the possible aetiology of this unusual presentation of endometriosis and review the literature on parasitic gynaecological tumours.

OBJECTIVES: Pulmonary Langerhans cell histiocytosis (PLCH) is a clonal disease, characterized by proliferation of Langerhans cells that derived from bone marrow infiltrating the lungs and other organs. Due to the rarity of the disease, the current understanding of the disease is insufficient, often misdiagnosed or missed diagnosis. This study aims to raise clinicians' awareness for this disease via summarizing the clinical characteristics, imaging features, and treatment of PLCH. METHODS: We retrospectively analyzed clinical and follow-up data of 15 hospitalized cases of PLCH from September 2012 to June 2021 in the Second Xiangya Hospital of Central South University. RESULTS: The age of 15 patients (9 men and 6 women, with a sex ratio of 3 to 2) was 21-52 (median 33) years. Among them, 8 had a history of smoking and 5 suffered spontaneous pneumothorax during disease course. There were 3 patients with single system PLCH and 12 patients with multi-system PLCH, including 7 patients with pituitary involvement, 7 patients with lymph node involvement, 6 patients with bone involvement, 5 patients with liver involvement, 2 patients with skin involvement, 2 patients with thyroid involvement, and 1 patients with thymus involvement. The clinical manifestations were varied but non-specific. Respiratory symptoms mainly included dry cough, sputum expectoration, chest pain, etc. Constitutional symptoms included fever and weight loss. Patients with multi-system involvement experienced symptoms such as polyuria-polydipsia, bone pain, and skin rash. All patients were confirmed by pathology, including 6 by lung biopsy, 3 by bone biopsy, 2 by lymph node biopsy, and 4 by liver, skin, suprasternal fossa tumor, or pituitary stalk biopsy. The most common CT findings from this cohort of patients were nodules and/or cysts and nodular and cystic shadows were found in 7 patients. Three patients presented simple multiple cystic shadows, 3 patients presented multiple nodules, and 2 patients presented with single nodules and mass shadows. Pulmonary function tests were performed in 4 patients, ventilation dysfunction was showed in 2 patients at the first visit. Pulmonary diffusion function tests were performed in 4 patients and showed a decrease in 3 patients. Smoking cessation was recommended to PLCH patients with smoking history. Ten patients received chemotherapy while 2 patients received oral glucocorticoid therapy. Among the 11 patients with the long-term follow-up, 9 were in stable condition. CONCLUSIONS PLCH is a neoplastic disease closely related to smoking. The clinical manifestations and laboratory examination are not specific. Pneumothorax could be the first symptom which is very suggestive of the disease. Definitive diagnosis relies on histology. There is no unified treatment plan for PLCH, and individualized treatment should be carried out according to organ involvement. Early smoking cessation is essential. Chemotherapy is the main treatment for rapidly progressing PLCH involved multiple organs. All diagnosed patients can be considered for the detection of BRAF^V600E gene and relevant targeted therapies have been implemented recently.

Aicardi syndrome is a severe congenital disorder characterized by infantile spasms, chorioretinal lacunae, and agenesis or hypogenesis of the corpus callosum. A 6 month old female had developed abnormal eye movement and seizures of the complex partial type and myoclonic type. MRI pictures of the patient revealed the presence of genu associated with agenesis of the rest of corpus callosum. A funduscopic examination revealed bilateral small, solitary, pale areas with sharp borders, some of which had minimal surrounding pigmentation (chorioretinal lacunae), especially clustered around the disc, and they were more prominent on the left side. We report here on the unusual findings of a complex partial seizure, myoclonic seizure and the atypical EEG finding in addition to the well-known characteristic clinical and imaging findings of a patient with Aicardi syndrome.

Tailgut cysts (TGCs) are rare congenital cysts that occur in the retrorectal or presacral spaces. Although most tailgut cysts have been reported as benign, there have been at least 9 cases associated with malignant change. We report herein on an unusual case of a 40-year-old woman with a carcinoembryonic antigen (CEA) -producing adenocarcinoma arising within a TGC who underwent surgical resection and local radiation therapy. Despite the complete resection, metastatic adenocarcinoma developed five months after surgery. CEA-producing adenocarcinoma from a TGC is extremely rare and only two cases, including this case, have been reported in the English medical literature. Besides CEA, the serum levels of CA 19-9 became markedly elevated in this patient. Given that the serum CEA level decreased to the normal range after complete resection of tumor and that the tumor recurrence was associated with a rebound of the CEA serum level, our case shows that serial measurements of serum CEA can be used for treatment planning and for assessing the patient's treatment response for this rare disease.

OBJECTIVETo report a rare case of ectopic mesonephric duct cyst with ectopic testicular malignancy and improve the diagnosis and treatment of the disease.

METHODSWe retrospectively analyzed the clinical data of a case of ectopic mesonephric duct cyst with ectopic testicular malignancy, reviewed relevant literature at home and abroad, and investigated the pathogenesis, diagnosis and treatment of the disease.

RESULTSA large cyst and the right ectopic malignant testis were removed via abdominal incision, and the left undescended testis was lowered into the scrotum. Pathological examination confirmed the lesion to be right ectopic mesonephric duct cyst with right ectopic testicular seminoma. No metastasis was found during a year of follow-up.

CONCLUSIONEctopic mesonephric duct cyst with ectopic testicular malignancy was a rare disease. Imaging examination contributes to its diagnosis, but it has to be confirmed by pathology. Surgical removal should be performed as early as possible and follow-up treatment depends on the pathologic type and stage of ectopic testicular malignancy.
