This is the cognitive process of integrating logic and knowledge into a series of stepwise decisions. All lesions that cannot be excluded initially should be included in the differential diagnosis, followed by laboratory tests and additional investigations to narrow the diagnosis The clinician may miss the diagnosis of this lesion due to its rarity. CS should be considered in the differential diagnosis of any subcutaneous nodules, especially in the head and neck region. The diagnosis of CS is mainly based on the histopathologic examination Lip swelling may be related to a local or systemic condition, and it can be the earliest manifestation of a systemic disease. The differential diagnosis can be simplified by grouping findings into broad categories: trauma, inflammation, infection, metabolic diseases, neoplasm and idiopathic conditions (Box 1) Differential Diagnosis of Oral Pigmented Lesions Evaluation of a patient presenting with a pigmented lesion should include a full medical and dental history, extraoral and intraoral examinations, and laboratory tests.2 The history should include the onset and duration of the lesion, the presence of associated skin hyperpigmentation Sarcoidosis causes granulomatous lesions to appear. Peutz-Jeghers syndrome causes multiple brown-pigmented macules on the lips, which can indicate intestinal polyposis

Differential Diagnosis. More than 180 conditions may present with lip swelling 1 and the pertinent diagnostic features do not always appear simultaneously. In addition to use of a standardized approach to the evaluation of an oral mucosal lesion, 2 6 main questions can be used to categorize most conditions or diseases associated with lip swelling (Fig. 2) The features of a variety of oral lesions are discussed and compared, to help clinicians in establishing an appropriate differential diagnosis. This report describes a lesion of the upper lip that was definitively diagnosed by histologic examination as a mucocele or mucus retention phenomenon. The usual location of mucoceles is the lower lip Differential diagnosis. The clinical presentation of a slow-growing, non-ulcerated asymptomatic mass was consistent with a neoplastic process. The differential diagnosis of a slow-growing mass in the upper lip includes benign tumours arising from minor salivary glands; the most common is pleomorphic adenoma, but other less common types such as basal cell adenoma, myoepithelioma, oncocytoma and. •Differential diagnosis of oral ulcerations with special emphasis on the diagnosis, etiology and management will be presented in a case-based format. •Immune-mediated, traumatic and neoplastic ulcerations will be illustrated Superficial lesions take on a bluish to translucent colour because of the thin layer of epithelium covering the bluish capillaries. Deeper lesions are usually the same colour as the rest of the lip as they are covered with a thicker layer of tissue. Bleeding into the lesion may cause a bright red colour and may occasionally resemble a haemangioma

Calibre persistent labial artery (CPLA) usually presents as an asymptomatic papule on the lower lip and can be easily misdiagnosed as a mucocele, haemangioma, venous lake, varix or fibroma. When it is ulcerated, squamous cell carcinoma is the most usual differential diagnosis. Here, we report a case of a 25-year-old woman with no previous relevant medical history who presented with a complaint. Squamous cell carcinoma (SCC) is a malignant tumour arising from the keratinising cells of the epidermis. It is slow growing, locally invasive and has the potential to metastasise to other organs of the body. We report an unusual presentation of a rapidly enlarging, well-differentiated SCC on the upper lip of a 75-year-old woman. Rapidly enlarging skin lesions in specialised areas pose great. Nasal Septum. Development of the nose and the nasal cavities occurs between 3 and 10 weeks of gestation (, 2 3).The nasomedial processes fuse in the midline with the frontal prominence, and the result is the formation of the frontonasal process, which gives origin to the columella, philtrum, upper lip, nasal bones, cartilaginous nasal capsule, and midline superior alveolar ridge (, 2)

Due to its clinical characteristics, the differential diagnosis commonly includes non-melanocytic skin lesions such as pyogenic granuloma, hemangioma or dermatofibroma [7, 11]. Spitz tumor can be rarely congenital [ 12 ] or it may arise either de novo or in association with a pre-existing melanocytic nevus [ 13 ] short palpebral fissures, smooth philtrum and thin upper lip. Hence, in the majority of affected individuals FASD is a diagnosis of exclusion. The differential diagnosis of both the dysmorphological and neurobehavioral aspects of FASD is wide.

A biopsy is rarely needed for diagnosis. Histologically, these lesions consist of subcorneal pustules filled with neutrophils, fibrin, and rare eosinophils. 63 The differential diagnoses of transient benign pustular disorders in the neonate are summarized in Table 7.2. These benign conditions should be distinguished from neonatal staphylococcal. O ral white lesions are a common clinical finding; in a recent study of more than 17 000 people in the United States, these lesions were found in 27.9%.1 The lesions represent a wide spectrum of diagnoses of varying seriousness, ranging from traumatic keratosis to dysplasia and squamous cell carcinoma. Although there are classical features associated with each diagnosis, appearances overlap. DIFFERENTIAL DIAGNOSIS. Considering the various etiologies of white spot lesions, it is imperative to establish a proper diagnosis. This is based on a thorough review of dental and medical history, and clinical examination evaluating the location, symmetry, outline form, depth and opacity of the lesion
