[Dual ectopic thyroid: subclinical hypothyroidism after extirpation of a submaxillary mass]. / Ectopia tiroidea dual: hipotiroidismo subclínico tras exéresis de una masa submandibular.

Ectopic thyroid tissue is a rare clinical entity, and more so when it is present in two different locations. We present the case of a 38-year-old euthyroid woman with submandibular and lingual ectopic thyroid tissue in the absence of a normally located thyroid gland, diagnosed after the extirpation of an asymptomatic mass misdiagnosed as a neoplasm of the submaxillary gland. Despite its low frequency, the possibility of ectopic thyroid should be considered when making a differential diagnosis of neck masses, using ultra-sound, thyroid scan and ultrasound-guided fine-needle aspiration biopsy.

Ectopia tiroidea dual: hipotiroidismo subclínico tras exéresis de una masa submandibular / Dual ectopic thyroid: subclinical hypothyroidism after extirpation of a submaxillary mass

La ectopia de tejido tiroideo es una entidad clínica poco frecuente, y más aún cuando se presenta en 2 localizaciones diferentes. Se presenta el caso de una mujer de 38 años a la que se diagnosticó ectopia tiroidea dual: submandibular y lingual, tras la exéresis de una masa cervical de crecimiento rápido sospechosa de neoplasia de la glándula submaxilar. A pesar de su baja frecuencia, la posibilidad de ectopia tiroidea se debe considerar cuando se realiza un diagnóstico diferencial de masas cervicales mediante ecografía, gammagrafía tiroidea y punción-aspiración con aguja fina guiada por ecografía (AU)

[Prostatic abscess: report of a case and review of the literature]. / Absceso prostático: revisión de la literatura y presentación de un caso.

Prostatic abscess is an uncommon entity nowadays due to widely use of antibiotics, however, in some patients, because of the seriousness, a quick diagnosis and interventionist treatment is required. We report a case of a 78 year-old male patient who had a torpid evolution and needed an urgent prostatectomy. We review ethiopathogenic factors, clinical findings, diagnosis and treatment of this uncommon entity.

[Melanosis of the bladder: a very uncommon entity]. / Melanosis vesical: una entidad de muy infrecuente presentación.

Melanosis of the bladder is a rare entity characterized by anomalous deposits of melanin-containing pigment on the vesical urothelium without melanocytic atypia or associated malignant melanoma. To our knowledge and following such strict criteria, there are only five cases previously reported. The biological potential of this entity is uncertain because of the rarity of their. We report one case of simple melanosis of the bladder confirmed by histological examination and inmunohistochemistry analysis. We believe that recognition of this entity is important.

[Angio-invasive disseminated aspergillosis: autopsy diagnosis in leukemic patients]. / Aspergilosis diseminada angioinvasiva: diagnóstico necrópsico en pacientes leucósicos.

We report on two patients with acute lymphoblastic leukemia in induction chemotherapy, who developed a sepsis which led, in both cases, to death following the appearance of neurological symptoms suggesting CNS affectation. Autopsy revealed an angioinvasive disseminated aspergillosis affecting lungs, brain, myocardium, kidneys, thyroid glands in both cases, and endocardium, urinary bladder, lymph nodes, alimentary tract, nasal sinuses in one of the cases. Microbiology study of necropsic tissue showed Aspergillus flavusoryzae and likewise Candida albicans in one case. The latter finding suggest a combined fungal sepsis caused to candida and aspergillus.
