RATIONALE: Low-grade adenosquamous carcinoma (LGASC) is a rare subtype of metaplastic breast carcinoma which is generally recognized as a characteristic subgroup of triple-negative breast cancers previously. However, in this study, we reported for the first time a case of LGASC with hormone receptors expression. PATIENT CONCERNS: Pathological analysis of breast tumor specimen obtained by a 42-year-old female patient was performed. Morphologically, it composed of glandular structures with scattered squamous differentiation accompanied by haphazard arrangement of spindle cell stroma...

A healthy 50-year-old woman had a tattoo performed on the posterior aspect of her neck and another on the dorsum of her left foot. Several weeks later, she noted redness, tenderness, and intense pruritis at both tattoo sites. Treatment with cephalexin and hydrocortisone cream was instituted, without success. Within a few months, the red, but not black, pigment had disappeared from both tattoos and was replaced by pale areas of scarring. Persistently enlarged left supraclavicular and suboccipital lymph nodes were excised 7 and 10 months after receipt of the tattoos, respectively...

Acute myocarditis is a potentially fatal cardiac pathology that is thought to cause sudden death through arrhythmia and cardiac failure. Of the different subtypes, lymphocytic myocarditis is the most common form. The pathophysiology of myocarditis can be generally diffuse or focally involve the ventricles, but less frequently affects the atria. Although the clinical literature reports isolated atrial myocarditis as a cause of atrial fibrillation and enlargement, there is scant postmortem literature on the findings of this pathology...

Insulin-like 3 (INSL3) is a hormone produced by Leydig cells (LCs) and leads to physiological testicular descent during embryonic development. We investigated the expression of INSL3 by immunohistochemistry in normal LCs, in Leydig cell tumor (LCT) (n=17 including 15 testes and 2 ovaries) and in Leydig cell hyperplasia (LCH) (n=10). Normally distributed LCs showed strong immunostaining in the cytoplasm in all cases. All 10 cases (100%) of LCH were strongly and diffusely positive in the intertubular areas. Six cases of LCH had nodules raging in size from 0...

We have previously reported that oral biofilms in clinically healthy smokers are pathogen-rich, and that this enrichment occurs within 24 h of biofilm formation. The present investigation aimed to identify a mechanism by which smoking creates this altered community structure. By combining in vitro microbial-mucosal interface models of commensal (consisting of Streptococcus oralis, Streptococcus sanguis, Streptococcus mitis, Actinomyces naeslundii, Neisseria mucosa and Veillonella parvula) and pathogen-rich (comprising S...

OBJECTIVE: The aim of this study was to compare the expression of proliferative markers and apoptosis-associated proteins in the oral mucosa adjacent to bone sequestrum associated with osteonecrosis (ON) of the jaws and florid osseous dysplasia (OD). STUDY DESIGN: Oral mucosal samples derived from surgical procedures performed for treatment of ON and OD (10 cases each) were retrieved. Histologic analysis was done on hematoxylin and eosin-stained slides; immunohistochemical reactions against epidermal growth factor (EGF), keratinocyte growth factor (KGF), vascular endothelial growth factor (VEGF), Bcl-2 protein, interleukin-6 (IL-6), and Ki-67 antigen were performed with the immunoperoxidase technique...

Syphilis is a multi-stage, sexually transmitted disease caused by the spirochete Treponema pallidum (Tp). Considered broadly, syphilis can be conceptualized as a dualistic process in which spirochete-driven inflammation, the cause of clinical manifestations, coexists to varying extents with bacterial persistence. Inflammation is elicited in the tissues, along with the persistence of spirochetes to keep driving a robust immune response while evading host defenses; this duality is best exemplified during the florid, disseminated stage called secondary syphilis (SS)...

The funeral procession of Sheng Xuanhuai (, 1844-1916) - the renowned Qing scholar-official, financier, and "father of Chinese industrialism" - meandered through the streets of Shanghai on 18 November 1917. The funeral was a grand event, one that was purportedly documented in film, later to be distributed as the first "news short-film" () in China. The North China Herald reported on the event in some detail, at times in rather florid language, and suggested that "the cortege was splendid and impressive, bringing back the days of the Manchu emperors...

Aldosterone-producing adenoma (APA), a major subtype of primary hyperaldosteronism, the main curable cause of human endocrine hypertension, involves somatic mutations in the potassium channel Kir3.4 (KCNJ5) in 30% to 70% of cases, typically the more florid phenotypes. Because KCNJ5 mutated channels were reported to be specifically sensitive to inhibition by macrolide antibiotics, which concentration dependently blunts aldosterone production in HAC15 transfected with the G151R and L168R mutated channel, we herein tested the effect of clarithromycin on aldosterone synthesis and secretion in a pure population of aldosterone-secreting cells obtained by immunoseparation (CD56(+) cells) from APA tissues with/without the 2 most common KCNJ5 mutations...

Neuropsychiatric symptoms in Alzheimer's disease are among the most disabling and difficult aspects for caregivers and treating health professionals to manage. Despite the high prevalence of these behaviors, little is known about the factors which lead some patients to develop florid behavioral symptoms while others may progress to severe dementia without such phenomenon. We examined whether regional brain volumes as measured by cortical thickness would predict the presence or absence of disinhibition in patients with Alzheimer's disease...

Tardive dystonia (TDt) is a debilitating side effect of long-term antipsychotic treatment. Even though TDt is associated with increased psychiatric morbidity, mortality, and severely decreased quality of life, there are no treatment modalities for TDt. Clozapine has been used as a treatment option for TDt in patients with schizophrenia. Interestingly, several recent case reports have indicated that it can enhance or induce TDt. We report a case of clozapine-associated TDt that was treated with low-dose aripiprazole (0...

BACKGROUND: Acute appendicitis is a very common surgical emergency. Most commonly, the histopathological findings of the appendix reflect the normal pathophysiology of appendicitis that starts with the luminal obstruction and culminates in florid suppurative, gangrenous or perforated appendix. The treatment is usually straightforward and consists of surgery and antibiotics. Uncommonly, unusual pathologies are identified and require specific management. The literature is scanty about the unusual findings...

OBJECTIVE: Gynecomastia is a common finding in the male population which is mostly idiopathic. The aim of our study was to analyze the histological differences in young and old patient groups and its association with recurrence rates. METHODS: Three hundred and five gynecomastia patients (555 breasts) undergoing surgical treatment from 1997 to 2015 were divided into four groups: Group 1: 13-17 years, Group 2: 18-30 years, Group 3: 31-49 years and Group 4: 50-83 years...

When hysterectomy is performed for chronic pelvic pain, routine pathology examination often provides no explanation. However, analysis of small uterine nerves using immunostains may help to address this deficiency. Small uterine nerves tend to be sparse or absent in wide areas of normal myometrium. Some studies of uterine nerves have suggested that endometriosis, adenomyosis, and fibroids are not inherently painful, with increased small nerves in the inner uterine wall associated with the history of pelvic pain...

The cellular mechanisms underlying the microvascular dysangiogenesis of bronchopulmonary dysplasia (chronic lung disease of the newborn) remain largely undetermined. We report unusual pulmonary vascular findings in a 27-week-gestation male newborn who died on the second day of life from intractable respiratory failure, following a pregnancy complicated by prolonged membrane rupture and persistent severe oligohydramnios. As expected, postmortem examination revealed pulmonary hypoplasia (lung/body weight ratio: 2...
