La hiperplasia estromal seudoangiomatosa es una lesión mamaria poco frecuente y de carácter benigno. Se caracteriza por un sobrecrecimiento de tejido conectivo fibroso que produce numerosos espacios que semejan estructuras vasculares. Generalmente afecta a mujeres en edad reproductiva, aunque se ha descrito en pacientes de edades comprendidas entre los 12 y los 75 años. Puede presentarse bien como un hallazgo incidental en el estudio histológico tras una cirugía por patología benigna o maligna, bien como una tumoración mamaria indolora, simulando un fibroadenoma, o bien como una gigantomastia o deformidad que se hace más evidente al tener en cuenta la mama contralateral. La biopsia percutánea guiada por ecografía permite detectar la naturaleza de la lesión con certeza y descartar patología maligna, como el angiosarcoma de bajo grado. El tratamiento es quirúrgico y abarca tanto la exéresis quirúrgica de la lesión como la mastectomía con reconstrucción protésica. Se describe una serie de 3 casos con diferente presentación clínica y tratamiento. El primer caso fue un hallazgo radiológico e histopatológico relacionado con una deformidad y asimetría mamarias, mientras que los 2 últimos casos se manifestaron como una tumoración mamaria palpable, única e indolora (AU)
Pseudoangiomatous stromal hyperplasia is a rare benign mammary lesion. It is characterised by an overgrowth of fibrous connective tissue that produces numerous spaces resembling vascular structures. This lesion usually affects women of reproductive age but has been described in patients aged between 12 and 75 years. It may appear as an incidental finding in histological analysis after surgery for benign or malignant disease, either as a painless breast tumour, simulating a fibroadenoma, or as a gigantomastia or deformity that becomes more evident on comparison with the contralateral breast. Percutaneous ultrasound-guided biopsy allows definitive identification of the type of lesion and exclusion of malignant disease, such as low-grade angiosarcoma. Treatment is surgical and includes both surgical removal of the lesion and mastectomy with prosthetic reconstruction. We describe a series of three cases with different clinical presentations and treatment. The first case was a radiological and histopathological finding related to a breast deformity and asymmetry, while the remaining two cases presented as a palpable, single and painless breast tumour (AU)

Primary peripancreatic lymph node tuberculosis is an exceptional entity in immunocompetent patients, but its incidence is increasing in developed countries in recent years due to increasing immigration. It usually presents as a pancreatic mass and is misdiagnosed as pancreatic neoplasia in most cases, with the diagnosis of tuberculosis occurring after surgery. We report the case of a 38 year old Pakistani man with abdominal pain of several months duration, who was initially diagnosed with a pancreatic neoplasm after detecting a mass in the pancreatic isthmus by computed tomography (CT) and abdominal magnetic resonance imaging (MRI). However, after performing an endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNAB), the patient was diagnosed with peripancreatic lymph node tuberculosis. After receiving anti-tuberculous treatment, the patient presented clinical improvement, despite a small reduction in the lesion size. In conclusion, peripancreatic lymph node tuberculosis is part of the differential diagnosis of pancreatic neoplasia. Endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNAB) represents a valuable and useful diagnostic tool for detecting this pathology, avoiding surgeries with a high morbidity and mortality.
