Phacoemulsification in a highly myopic, single-seeing, post-vitrectomized eye with an anterior chamber phakic intraocular lens: a surgical challenge
DOI: 10.31744/einstein_journal/2026RC2213
ABSTRACT We report a case of a highly myopic patient with a single functional eye, previously vitrectomized, and implanted with an anterior chamber phakic intraocular lens (Artisan®), who underwent phacoemulsification with phakic lens explantation and posterior chamber intraocular lens implantation. The case illustrates the surgical challenges and highlights the importance of individualized planning in patients with multiple prior interventions and at high risk of complications.

Lymphatic malformations: formerly known as lymphangiomas. A rare case of two breast masses in different locations mimicking breast carcinomas
DOI: 10.31744/einstein_journal/2026RC2042
ABSTRACT Lymphatic malformations are benign disorders of the lymphatic system and represent a rare diagnosis in adulthood, particularly when involving the breast. This report describes the case of a 64-year-old patient referred to our service with two suspicious masses located in different areas of right breast. Imaging studies reinforced the suspicion of malignancy, and further investigation was conducted with an ultrasound-guided core needle biopsy, which confirmed the diagnosis of lymphatic malformation. As illustrated in this report, although lymphatic malformation may […]

Müllerian-type clear cell adenocarcinoma of the urethra: a case report
DOI: 10.31744/einstein_journal/2026RC1169
ABSTRACT Primary urethral carcinoma is a rare malignancy, particularly in women, that often presents at an advanced stage with nonspecific symptoms. Among the histological subtypes, clear cell adenocarcinoma is exceptionally uncommon, with approximately only 250 cases reported in the English literature, posing diagnostic and management challenges. We report a case of Müllerian-type clear cell adenocarcinoma of the urethra in a 58-year-old woman. Imaging studies excluded gynecological origins, suggesting derivation from a Müllerian duct remnant or metaplasia. Histologically, the tumor displayed […]

Severe bleeding diathesis after dental extractions: a complex case of coagulation disturbances in a patient with multiple myeloma
DOI: 10.31744/einstein_journal/2026RC1902
ABSTRACT This case report describes a male patient diagnosed with multiple myeloma who experienced significant bleeding from both the maxillary and mandibular dental sockets following dental extraction, lasting several days. Laboratory tests revealed prolonged prothrombin time and thrombin time, accompanied by reduced factor VII levels. Initial management with intravenous vitamin K and fresh frozen plasma failed to achieve hemostasis. Despite the risk of thrombosis, low-dose tranexamic acid was initiated, resulting in effective hemorrhage control and improved healing of the alveolar […]

Difficulties in diagnosing a pediatric patient with small intestinal bacterial overgrowth
DOI: 10.31744/einstein_journal/2026RC2117
ABSTRACT A 3.5-year-old female presented with a 10-month history of abdominal pain and distension, accompanied by frequent belching and flatulence. No nausea, vomiting, or nighttime awakening due to pain was reported, and the patient’s appetite remained intact. Growth and development were age-appropriate (weight: 16.2kg, height: 106cm). She was born at term without complications and had a normal neonatal screening. No comorbidities typically associated with small intestinal bacterial overgrowth (SIBO)—such as prior intensive care unit admission, immunodeficiency, food intolerance, Helicobacter pylori […]

Pulmonary artery aneurysm and tuberous sclerosis: case report
DOI: 10.31744/einstein_journal/2026RC0847
ABSTRACT Tuberous sclerosis is a rare and serious genetic disease, classically characterized by epilepsy, mental deficiency, and sebaceous adenomas; however, it may also be associated with the development of multiple tumors in various organs. Pulmonary artery aneurysm has rarely been described in the literature. This article reports a case of tuberous sclerosis in a 3 year old child with a pulmonary artery trunk aneurysm, cardiac rhabdomyomas, and a bicuspid aortic valve, a combination that has been rarely described in the […]

Laser therapy: palliative care for the Harlequin syndrome?
DOI: 10.31744/einstein_journal/2026RC1544
ABSTRACT Harlequin syndrome is a rare condition characterized by facial dysautonomia with anhidrosis, hemifacial blush, and other nonfacial manifestations without conventional treatment. This report presents a case study of the potential treatment of Harlequin syndrome using laser therapy. A single-case AB design was used, allowing for a systematic comparison between the baseline and intervention phases. The baseline phase involved data collection during a period without intervention (control condition), that is before laser therap. As evaluation criteria, a clinical assessment of […]

Thyroid cartilage resection surgery for metastases of clear cell renal cell carcinoma: case report and literature review
DOI: 10.31744/einstein_journal/2026RC2002
ABSTRACT Laryngeal cartilage is an exceptionally rare site of metastasis, with fewer than 63 cases reported in the literature; prostate, kidney, breast, and lung cancers are the most common primary tumors. In addition to this extreme rarity, most published reports are limited to descriptions of the lesion and radiologic findings, without detailing management strategies or follow-up outcomes. The limited number of studies exploring surgical intervention have primarily described superficial resections or conventional laryngectomies. In this context, this case report describes […]

Disseminated juvenile paracoccidioidomycosis: a case report and literature review
DOI: 10.31744/einstein_journal/2026RC1946
Abstract We report a case of juvenile paracoccidioidomycosis in a previously healthy patient and aim to raise awareness of its severe and atypical clinical manifestations. A 16-year-old male student, employed in automotive cleaning services, originally from Pará and residing in Embu das Artes, São Paulo, presented with progressive lymphadenopathy, jaundice, and signs of acute liver failure. He was admitted to a tertiary hospital, where imaging and histopathological analyses confirmed the diagnosis of paracoccidioidomycosis by identifying Paracoccidioides spp. on lymph node […]

Postoperative intestinal obstruction caused by staple-related internal hernia after laparoscopic appendectomy: a case report
DOI: 10.31744/einstein_journal/2026RC1256
Abstract Postoperative intestinal obstruction is most commonly associated with adhesions but may also arise from unusual causes such as surgical staples adhering to adjacent structures. Although the use of endoscopic staplers in laparoscopic appendectomy is effective and generally safe, it can occasionally result in complications, including intestinal obstruction. We report the case of a 41-year-old woman who underwent surgical treatment for pelvic endometriosis, including appendectomy, and subsequently developed intestinal obstruction caused by an internal hernia formed by the entrapment of […]
