Notes

Assessment involving polidocanol sclerotherapy along with laparoscopic deroofing inside the treatments for child symptomatic straightforward renal growths: A new long-term examine.
We advocate the use of electromyographic and auditory brainstem responses to monitor the inferior cranial nerves because the tumor often adheres to these nerves.

The abnormal expression of B-cell lymphoma-2 (Bcl-2) family members is often associated with the progression of the disease. SBI115 Bcl-2 inhibitors (eg, venetoclax) were first reported to inhibit the proliferation of malignant lymphocytes and have a significant effect on patients with chronic lymphoblastic leukemia, but research on myeloid tumors is relatively delayed. Venetoclax was approved in 2018 for the treatment of acute myeloid leukemia (AML) patients who were not suitable for high-dose chemotherapy. The approval of venetoclax is an advance in the treatment of hematological tumors.

Here we report a 64-year-old male with an increased white blood cell (WBC) count (39.0 × 109/L) and lymphocyte count (30.6 × 109/L) on physical examination in July 2014. The patients were diagnosed with chronic lymphocytic leukemia (CLL) through bone marrow (BM) smears and immunophenotyping without any cytogenetic or molecular abnormalities. Chlorambucil was prescribed, WBC was stable between 15 × 109/L and 25 × 109/L in the pensive use of targeted drugs with different mechanisms will not only improve the quality of life of patients, but also completely change the prognosis of patients with recurrent and refractory hematological malignancies.
Our case presents a challenge to traditional treatment. New drugs such as venetoclax have shown outstanding effects in this respect. High expression of Bcl-2 can identify the responders of venetoclax. These findings should be validated in future clinical trials. We fully believe that in the near future, the comprehensive use of targeted drugs with different mechanisms will not only improve the quality of life of patients, but also completely change the prognosis of patients with recurrent and refractory hematological malignancies.
Double primary lung cancer (DPLC) is a relatively rare type of lung cancers. According to whether the diagnosis interval between lesions is more than 6 months, it can be divided into synchronous DPLC (sDPLC) and metachronous DPLC (mDPLC). Here, we describe a case of sDPLC in which one of the components is a rare colloid adenocarcinoma (CA).

A 69-year-old male was admitted to the hospital due to chest distress and shortness of breath for 1 year, getting worse in the last 15 days.

Both HE staining and IHC supported the diagnosis of CA in the right lower lobe and moderately differentiated squamous cell carcinoma in the right upper lobe.

The patient was treated with 3 cycles of adjuvant chemotherapy with pemetrexed and lobaplatin after the right upper lobectomy, wedge resection of the right lower lobe and lymph node dissection under video-assisted thoracoscope.

Our plan was to follow him up with general physical examination, chest-abdomen CT and serum tumor markers every 6 months for 2 years. The patient was still alive until the last follow-up in November 2020.

CA of the lung is a rare primary lung adenocarcinoma. The diagnosis should be based on the patient's clinical characteristics, imaging examination and pathological characteristics, and also need to be differentiated from other mucinous adenocarcinomas. Interestingly, our patient developed not only a CA in the right lower lobe, but also a moderately differentiated squamous cell carcinoma in the right upper lobe.

Pulmonary artery intimal sarcoma is a rare tumor with exceptionally high mortality and easily misdiagnosed as pulmonary thromboembolism pulmonary thromboembolism (PTE) due to the nonspecific clinical presentation and symptom. Misdiagnosis or untimely diagnosis makes the disease progress to an advanced stage and eventually leads to a poor prognosis.

A 37-year-old Chinese female presented with chest tightness and dyspnea for 3 months. Echocardiography and chest computed tomography revealed an intraluminal obstruction of the pulmonary arteries. Tests of serum tumor makers showed slight elevation for carbohydrate antigen-125, and α-fetoprotein. PTE was suspected according to the radiological and laboratory findings.

Microscopic findings of the presumed thrombus showed prominent myxoid and edematous background with atypical spindled cells and curvilinear vascularity. Immunohistochemical staining demonstrated that the atypical spindled cells were positive for vimentin but negative for CK, S100, SMA, desmin, CD68, STAT6, CD34, β-catenin, ALK-p80, p53, and MDM2. According to the radiological and pathological findings, the diagnosis of fibrosarcoma of pulmonary artery was made.

The patient underwent surgical resection and the mass was excised as completely as possible.

Follow-up information showed no evidence of recurrence or metastasis after 3 months postresection.

Because of the low incidence rate, nonspecific clinical symptoms, and radiological findings, primary fibrosarcoma of the pulmonary artery is commonly misdiagnosed as PTE. Pathological examination is necessary to confirm the diagnosis.

Chromobacterium violaceum is a motile gram-negative bacterium. This bacterium commonly grows in tropical or subtropical areas in sewage and can cause opportunistic infections.

A 50-year-old Chinese man had a skin ulcer in the middle of his left leg in front of the tibia. The diameter of the wound was 3.0 cm, the exudation was obvious, and necrotic tissue was attached to the wound. One week previously, he was working in a field where he accidentally punctured his left leg.

C violaceum infection was diagnosed as per the results of pathogen culture from the infection site.

He was treated with piperacillin/tazobactam (3.375 g/12 h iv) and levofloxacin (0.5 g/24 h iv) for 5 days.

The patient showed good response to therapy and was discharged on day 18 after wound healing.

C violaceum rarely infects humans. When an infection is suspected, samples should be immediately sent for microbial culture. Timely treatment on the basis of drug sensitivity test results can prevent further complications.
