Direct Infiltration

These manifestations of cancer are not due to direct infiltration or invasion, but are usually mediated by hormonal or other aberrant signaling. The chapter deals with the more common of these that effect the endocrine, neurological , haematological or dermatological systems. There are many of these which are relatively uncommon but bring a differential diagnosis of underlying malignancy.

Muscle Biopsies

An eight-month-old, male, neutered, domestic short hair cat was presented for further investigation of white granuloma-like lesions on the tongue and recent onset regurgitation. The owner reported that the cat had an ‘unusual’ gait. Moderate increases in alanine aminotransferase, aspartate aminostransferase and markedly elevated creatine kinase were present. Thoracic radiographs revealed moderate-to-severe oesophageal impaction, cardiomegaly and an irregular appearance of the diaphragm. Endoscopy revealed a distended oesophagus with accumulation of ingesta. Difficulties were encountered when passing the endoscope through the cardia. Histology of the white granuloma-like lesions were pathognomonic of calcinosis circumscripta. These features raised the suspicion of feline muscular dystrophy. Muscle biopsies and electromyography were declined, and the patient was euthanased. Postmortem examination, histopathology and immunohistochemistry were suggestive of dystrophin-deficient muscular dystrophy (DDMD). This case emphasises the importance of including DDMD as a differential diagnosis for regurgitation and lingual calcinosis circumscripta in cats.

Dermal Lesions

AbstractAcute febrile neutrophilic dermatosis (Sweet‘s syndrome) is a dermatological entity, which may be associated with malignancies, drugs, and infections and which is characterized by high fever, elevated neutrophils, and tender erythematous skin lesions. Involvement of the nervous system – Neuro-Sweet syndrome (NSS) - is rare, manifesting most commonly with an encephalitic syndrome in addition to fever and dermal lesions. Here, we report an unusual case of NSS in a Caucasian male patient in the setting of B-cell-lymphocytosis, with encephalitis preceding dermal lesions. Symptoms resolved completely in response to corticoids.NSS is a rare, but important differential diagnosis in the work-up of febrile aseptic meningoencephalitis unresponsive to anti-infectious treatment. Due to its rarity and clinical variability, diagnosis of NSS might be challenging. Knowledge of this entity may facilitate proper diagnosis and differentiation from conditions with similar clinical presentation, especially Neuro-Behçet‘s disease. It may further lead to early detection of a potentially underlying malignancy and help in initiating adequate therapy.

Leptomeningeal Infiltration

ABSTRACT: Carcinomatous meningitis is defined as leptomeningeal infiltration by malignant cells. A case of carcinomatous meningitis, originally diagnosed as viral meningitis, is presented here to highlight the importance of maintaining a broad differential diagnosis in patients with evidence of meningeal irritation. Clinical and laboratory clues that suggest a diagnosis of carcinomatous meningitis in a patient with meningeal irritation include the presence and type of underlying malignancy (more common with breast cancer, lung cancer, and melanoma), absence of fever, presence of radicular pain, evidence of both cranial and spinal involvement, consistent cerebrospinal fluid (CSF) findings (increased opening pressure, elevated protein concentration, decreased glucose, increased white cell count), and supportive neuroimaging. Diagnosis is based on positive CSF cytology results, which may require multiple lumbar puncture procedures to obtain. For patients with a known primary malignancy who present to the emergency department with symptoms and/or signs of meningeal irritation, carcinomatous meningitis should be included in the differential diagnosis.

Background: Palm and sole skin eruptions have a broad differential diagnosis. It is particularly important to recognize common causes as well as their association with certain chemotherapy regimens such as Capecitabine. Case report: A 79-year-old woman presented with a painful rash on her hands and feet for 1 week. She had metastatic colon cancer and was in her third week of treatment with capecitabine. Her diagnosis was a medication side-effect from chemotherapy. Capecitabine was stopped and she had some clinical improvement over the next two days. She was discharged with oncology follow up for resumption of Capecitabine at a lower dose with improvement in her rash 3 weeks later.  Discussion: Skin rashes are a commonly encountered complaint in patients in the inpatient and outpatient setting. It is important to maintain a broad differential diagnosis in those with rashes of the palmoplantar surfaces of the hands and feet. Recognizing skin changes as a possible manifestation of underlying malignancy or a medication side-effect is key in appropriate diagnosis and treatment.

Microscopic Diagnosis

The broadest application of transmission electron microscopy (EM) in diagnostic medicine is the identification of tumors that cannot be classified by routine light microscopy. EM is useful in the evaluation of approximately 10% of human neoplasms, but the extent of its contribution varies considerably. It may provide a specific diagnosis that can not be reached by other means, but in contrast, the information obtained from ultrastructural study of some 10% of tumors does not significantly add to that available from light microscopy. Most cases fall somewhere between these two extremes: EM may correct a light microscopic diagnosis, or serve to narrow a differential diagnosis by excluding some of the possibilities considered by light microscopy. It is particularly important to correlate the EM findings with data from light microscopy, clinical examination, and other diagnostic procedures.

Healthcare professionals require a thorough understanding of stuttering since they frequently play an important role in the identification and differential diagnosis of stuttering for preschool children. This paper introduces The Preschool Stuttering Screen for Healthcare Professionals (PSSHP) which highlights risk factors identified in the literature as being associated with persistent stuttering. By integrating the results of the checklist with a child’s developmental profile, healthcare professionals can make better-informed, evidence-based decisions for their patients.

Threshold Duration

Previous findings on the threshold for tones as a function of their duration have suggested that such functions may be systematically affected by sensori-neural hearing losses of cochlear origin. The present series of investigations was designed to explore this relation further and to determine also whether the amount of hearing loss present has any effect upon the results which are obtained. Preliminary studies were also carried out on a conductively impaired listener to indicate whether hearing losses of this type affect the threshold-duration function. The results indicate that the threshold-duration function is systematically affected by sensori-neural hearing losses of cochlear origin. This effect is manifested by a progressive shortening of the time constant relating threshold to duration and is not uniquely related to the amount of hearing loss present. The results obtained from the conductively impaired listener suggested that this type of hearing loss has no effect on the threshold-duration function, thereby implying that such functions may contribute significantly to the differential diagnosis of auditory disorders.
