Pseudoachalasia as a paraneoplastic event in a patient with Hodgkin’s disease

Pseudoachalasia or secondary achalasia (5% of achalasias that are deemed primary achalasias) is an esophageal motor disorder with manometric criteria for achalasia, but it appears in the context of an underlying pathology that can be attributed to its origin. Usually appears in >60 years with rapid evolution of symptoms (<1 year). The main cause of pseudoachalasia is neoformative etiology, but there are others. Our patient started with rapid progression dysphagia and was diagnosed with type II achalasia within a Hodgkin's lymphoma. In the radiological-metabolic studies, disease involvement was ruled out as an extrinsic compression of the esophagogastric junction as well as signs of its activity at this level. Chemotherapy has not been shown to play a role in the development of this pathology. On the other hand, radiotherapy has been associated with an esophageal motor disorder, but, in our case, it was after its onset. Therefore, we propose that the mechanism of pseudoachalasia in our case is a paraneoplastic event. This hypothesis is related to other similar cases reported, and it reflects the importance of continuing to investigate this clinical condition that is indistinguishable by manometry from primary achalasia. In addition, it usually presents differential clinical characteristics whose early recognition has implications for the diagnostic, therapeutic, and prognostic management of the patient. (AU)

Recurrent hemobilia secondary to extrahepatic biliary tract cholangiocarcinoma. A diagnostic challenge.

The etiology of hemobilia has mainly iatrogenic (>50%), followed by traumatic causes. Others are biliopathy due to portal high pressure, or neoplastic or infective biliopathy. In the case of non-clear hemobilia, direct-vision-cholangioscopy can change the management in >34% of cases. Our patient had episodes of obstructive hemobilia with secondary cholangitis without objectifying underlying pathology. When she was referred to our center, SpyGlass®-cholangioscopy identified the suspicious lesion compatible with early-stage cholangiocarcinoma despite the diagnostic delay. In conclusion, it is important to keep in mind the neoformative etiology as a potential cause of hemobilia of unclear origin, in which case, cholangioscopy (SpyGlass®) can contribute to the recognition of the signs of malignancy of the lesion and, therefore, to the diagnosis.

Mesalazine-induced esophageal ulcers. a rare adverse effect.

31-year-old woman. Diagnosis of ulcerative proctitis in February/2022. Calprotectin 1832 µg/g. Colonoscopy: erythematous, friable and erosive mucosa up to 10 cm from the anal margin. Pathology: compatible with ulcerative colitis with moderate activity. Start of oral mesalazine (3 gr/24 h granules) and topical (1 gr/24 h suppository). After three months, she achieved clinical remission. Calprotectin 57 µg/g. Two months later, she consulted for solid dysphagia, loss of 10 kg, and low-grade fever for a month. Fifteen days before, she went to an emergency room where Prednisone 50 mg/24 h was started. On the day of the assessment, she was receiving 30 mg with no improvement. The next day, gastroscopy showed 6-12 mm esophageal ulcers with non-confluent shallow geographic borders, biopsies were taken. Viral serologies and HLA B51 were requested. Given the severity of the symptoms, empirical treatment was started with Valaciclovir 1 g/12 h. Serologies: IgG for Ebstein Barr virus, cytomegalovirus and herpes virus with negative IgM. Cytomegalovirus viral load: <30 IU/ml. Pathology: acute extensively ulcerated esophagitis, inflammatory infiltrate and some eosinophils with negative histochemical staining for fungi, cytomegalovirus and herpes virus I and II. HLA B51 was negative. Valaciclovir and mesalazine are discontinued after seven days given the known relationship of the latter with low-grade fever and, exceptionally, with esophageal pathology. Three days later, the patient reported clear improvement in dysphagia from the day the mesalazine was discontinued. After eight months, she was still asymptomatic. Upon resolution of the symptoms, control gastroscopy was not performed, and mesalazine has not been reintroduced due to its probable causal association. Mesalazine has an excellent safety profile. Adverse effects include fever, headache, diarrhea and.

Histiocytic sarcoma of the esophagus.

A 20-year-old male with no medical history of interest who goes to the emergency room because of retrosternal pain, odynophagia, dysphagia, and fever. On physical examination: 37.7ºC axillary temperature, bad general condition, and central chest pain on palpation. In the blood test: 16,200x10^6/L white blood cells, 12,800x10^6/L neutrophils, and 11.66mg/dL C reactive protein, with the rest of the complete blood count, coagulation, and biochemistry within normal values.
