Adenoid basal epithelioma of the uterine cervix in 21-year-old patient. Report of a case with histologic and immunohistochemical study.

A case of adenoid basal epithelioma (ABE) of the uterine cervix in 21-year-old woman is reported. The patient's age appears to be lowest among cases of ABE reported to date. The tumor showed typical histologic features of ABE and was associated with CIN3. In addition, rare tumor cells had surface cilia-appearing structures suggesting tubal differentiation. Immunohistochemically, the tumor was reactive for p63, CD10, ER, PR, p16 and bcl-2, and negative for CEA. Thus, the immunophenotype also suggests possible partial tuboendometrioid differentiation in the glandular component of the lesion. It further indicates, along with finding of associated CIN, a role of oncogenic HPV in pathogenesis of ABE.

[Sinusal cystic adenoid carcinoma. Study of a case].

One case of adenoid cystic carcinoma of maxillary sinus is reported. Is a malignant epithelial tumor which develops in major and minor salivary glands. Is the malignant tumor most common in the minor salivary glands. Incidence in the paranasal sinuses lies between 2-5% of all malignant tumors. These tumors grow by extensive local infiltration and perineural spread is a common feature. They are very high malignancy tumors.

[Adenoid basalioma of the axilla].

Basal cell carcinoma is the most common malignant skin tumor in the elderly. It occurs predominantly in the head and neck region. As is well known, skin exposed to sunlight is the most frequent location, but basal cell carcinoma can arise elsewhere. This report describes a 81-year old woman who developed a basal cell carcinoma of the adenoid subtype in the axilla. Before surgical excision, the lesion was diagnosed cytologically. This diagnosis was confirmed by histology. Cytologic examination of skin lesions whose size and location allow this procedure appears to be the sole conservative means of achieving a presurgical diagnosis. The technique is simple. The morphologic differential diagnosis of basal cell carcinoma is discussed.

[Fine structure of glioblastoma multiforme with "adenoid formation"].

Glioblastoma multiforme with "adenoid formation" (Kepes) in the temporal lobe of a 70 year old man was presented. In addition to the classical features of glioblastoma multiforme, the tumor presented a pattern of anastomosing trabeculae of polygonal cells, mimicking epithelial tubules, in a myxoid stroma. On electron microscopic examination, the tumor cells were devoid of well-developed cytoplasmic processes. The cytoplasm of some tumor cells contained glycogen particles and lipid vacuoles in addition to usual organelles. The cell surface was partly covered by basal lamina associated with half desmosomes and had occasional filopodia-like cytoplasmic projections. A few tumor cells contained a dense intracytoplasmic accumulation of glial filaments. Intercellular junctional complexes were poorly developed. There was no evidence of differentiation of tumor cells toward ependymal cells or epithelial cells. These electron microscopic findings suggest that this tumor is predominantly composed of immature astrocytes. In spite of a superficial resemblance to adenocarcinoma on light microscopy, the tumor cells are devoid of the differentiating features of epithelial neoplasms, and their ultrastructure is essentially similar to that of glioblastoma multiforme.

Adenoid squamous cell carcinoma of the nasopharynx and neck region.

Adenoid squamous cell carcinoma (ASCC) is a rare variant of squamous cell carcinoma. This tumor most commonly occurs in the skin of the head and neck and rarely in the vermillion of the lip, vulva, and oral cavity. This report of two patients includes the first (to our knowledge) case of ASCC in the nasopharynx. It also describes the immunocytochemical and ultrastructural features of this tumor. Our findings and a review of the literature indicate that ASCC of the upper aerodigestive tract is associated with an aggressive behavior and poor prognosis, in contrast with ASCC of the skin.

Scanning electron microscopy of damage to the cecal mucosa of turkeys infected with Eimeria adenoides.

White Wrolstad turkeys were each inoculated with 100,000 Eimeria adenoides oocysts and killed on days 4-14 postinoculation. Tissue samples, obtained from 4 areas of the ceca comparable to areas examined in chickens infected with E. tenella in previous studies, were processed by a modification of the osmium-thiocarbo-hydrazide-osmium technique and examined with a scanning electron microscope. The pathologic situation found in turkeys was slightly different from that in the ceca of chickens infected with E. tenella. The mucosal lesions are most severe at the proximal end of an infected cecum. Surface disruption was far less severe than with cecal coccidiosis in chickens of the same age exposed to an equal number of infective oocysts. Rupture of the epithelial cell often caused the mucosal surface to present a honeycomb appearance. Some specific stages of the life cycle were identified, including schizonts and oocysts.

The clinical significance of "adenoid" formations of neoplastic astrocytes, imitating metastatic carcinoma, in gliosarcomas. A review of five cases.

Five cases of supratentorial gliosarcomas occurring in middle-aged and elderly patients are reported. In the gliomatous portions of the tumors there were areas with clusters and ribbons of cuboidal cells forming a cribriform pattern and structures resembling ducts and glands of a metastatic adenocarcinoma. Where the adenoid structures were embedded in a mucoid matrix, an imitation of mucus-producing ("colloid") carcinoma was created. In one patient who had a large pelvic mass (later identified as a benign leiomyoma) the histology of the brain tumor suggested a metastatic müllerian carcinosarcoma. The pseudoglandular elements in each case could be identified as being composed of primitive astrocytes, partly by finding transitions to more mature and typical astrocytes and partly by positive staining with the immunoperoxidase method for glial fibrillary acidic protein (GFAP). The recognition of this morphologic variant of malignant glial tumors is important, particularly in patients of the age group in which primary carcinomas elsewhere in the body occur with increasing frequency. In such patients the correct diagnosis of their brain tumor can avoid the added post-craniotomy discomfort and expense of a "workup for a primary tumor."

Adenoid cystic carcinoma of the uterine cervix. A report of two cases.

Two new cases of adenoid cystic carcinoma of the uterine cervix are presented. The first patient, a 45-year-old woman, died from probable pulmonary metastases 1 year after presentation. The second, a 73-year-old woman, was alive, without evidence of disease, 6 months after presentation. Review of the literature and assessment of these 2 cases suggest that this tumour is radiosensitive, and the therapy advocated is radiotherapy followed by wide local excision.

[Tubular adenoid granulosa cell tumours - their histogenesis (author's transl)].

A brief general review of granulosa cell tumours is followed by reference to more specific data obtained from hospitalised patients of the authors over the past 36 years. A tumour form observed in one female patient, but never before reported, is described under the name of "tubular adenoid granulosa cell tumor". - Histogenetic theories and functionally paradoxical tumours are discussed, in that context. The point is made that histopathological results may be confusing under certain circumstances. - An attempt is made to find an explanation for the functional behaviours of the above paradoxical tumours.

Clinical audit on tonsils and adenoid surgery. Is day surgery a reasonable option?

Four hundred and five patients who underwent tonsillectomy and/or adenoidectomy over a 27-month period were reviewed retrospectively to determine local patient characteristics and complication rates. The predominance of adult patients (mean age of 23.8 years), male subjects (male to female ratio of 2:1), and tonsillectomy cases (85.4%) were in contrast to studies reported in Western countries. Chronic tonsillitis or adenoiditis was the most common indication for surgery and the most frequent complications encountered were fever (20.0%) and haemorrhage (5.2%). Three patients (0.7%) had significant haemorrhage requiring a return to the operating theatre for haemostasis. Bleeding occurred within 6 hours in 2 patients and on the third postoperative day in 1 patient. The rate of haemorrhage was significantly higher in male patients (P = 0.038). The average duration of hospitalisation was 3.6 days. The main reasons for delayed discharge from hospital were retention for observation of pain and fever or for social or administrative purposes. Based on the results of the survey, day surgery for tonsillectomy and adenoidectomy would be feasible in Singapore provided patients are carefully selected and actively monitored for at least 6 hours after the operation.

[Oro-pharyngeal burn during electrodissection of the adenoid and tonsil].

We present a case of oro-pharyngeal burn which occurred during electrodissection of the adenoid and tonsil in a 5-year-old boy. We intubated the patient with an uncuffed spiral tube of appropriate size and noticed a slight gas leak during positive-pressure ventilation. Anesthesia was maintained with a mixture of 60% nitrous oxide, 40% oxygen and 2.5% sevoflurane. During manipulations of the right tonsil, orange-colored flame blew out about 5 cm from the mouth. Fortunately, the patient underwent the operative procedures without any further troubles, recovered fully from the grade 1 burn in the oral mucosa, and was discharged 23 days after surgery. The surgeons speculated that sevoflurane had been ignited. Although it is well known that sevoflurane is nonflammable in the concentration of clinical use, several reports show that sevoflurane is flammable in concentration of 10% under pure oxygen or nitrous oxide. We concluded that this accident was caused by electrocautery-induced ignition of the gauze packed into the larynx under a high concentration of oxygen which leaked through an uncuffed endotracheal tube. We have to bear in mind that any flammable substance may ignite when using electrocautery in a small space such as the mouth under oxygen-rich environment.

Serum immunoglobulin E levels in relation to adenoid surgery.

The adenoid tissue is an immunecompetent lymphoid organ, which has the capacity of reacting against numerous antigens. We have studied the influence that the elimination of the said tissue would have on the total IgE serum levels in 33 patients of an average age of 5 and criteria of adenoidectomy and in whom these levels were measured before and after surgery. We have not noticed any statistically significant differences in the IgE values after adenoidectomy with respect to those prior to surgery, which were normal. Adenoidectomy, like other authors have observed after tonsillectomy, does not alter the IgE serum values.

[Post-obstructive pulmonary edema after adenoid-amygdalectomy].

A two-years-old boy with Down's Syndrome and a small interauricular communication was given priority scheduling for adenoidectomy and tonsillectomy to correct subacute obstruction of the upper airway. The only noteworthy event during surgery was an SpO2 of 92% during mechanical ventilation with FiO2 of 0.5 from no apparent cause. The patient suffered acute respiratory insufficiency due to the post-obstructive pulmonary edema in the hours immediately following surgery. The incidence of post-obstructive pulmonary edema is higher than might be expected, as symptoms can be interpreted as aspiration pneumonitis or left ventricular failure. Given the high prevalence of adenoiditis and tonsillitis with varying degrees of airway obstruction in children, we consider it useful to report this case. Such patients should be monitored carefully in the early postoperative period.
