Appendicular Lymphoid Hyperplasia in the Differential Diagnosis of Acute Appendicitis: Sonographic Findings

2020 , WHITTLE, CAROLINA , Lizbet Pérez , Marcela Cortes , Margarita Switt , Javiera Aguirre , CASTRO MENDEZ, ALEX

Objectives: To describe sonographic findings of appendicular lymphoid hyperplasia (ALH) and to report demographic data of patients with ALH operated for acute appendicitis (AA). Materials and Methods: In a retrospective study, 694 biopsies of consecutive AA surgeries with previous ultrasonography (US) were reviewed, after selecting the ALH cases. Results: Twenty-five ALH cases were proved histologically (3.8% of appendectomies). The mean age was 13 years, with 84% under 20 years. US findings showed increased appendiceal diameter (average 7 mm) (82%), hypoechogenic pseudonodular mucosal thickening (50%), concentric parietal thickening (13%), and periappendiceal inflammatory changes (18%). In four cases, a normal appendix was noted on US, with two associated with intestinal intussusceptions. Conclusion: ALH is a benign entity most frequent in children that can predispose to AA. Both pathologies can increase the appendiceal diameter. In the pediatric group, ALH could be considered when hypoechogenic pseudonodular appendicular mucosal thickening in the absence of periappendiceal inflammatory changes occurs.

Ulcerated Keloid Secondary to a Coexisting Complicated Epidermal Inclusion Cyst: A Sonographic Diagnosis

2020 , Jaime Pérez-Wilson , WHITTLE, CAROLINA , Viviana García , Frances Norris , CASTRO MENDEZ, ALEX , Mario Hitschfeld

Keloid is a benign fibroblastic tumor that is most often secondary to tissue injury. The clinical presentation is a hard red or purple tumor, mostly itchy or painful. The clinical objectives are to report an ulcerated keloid secondary to a central or inner complicated epidermal inclusion cyst histologically proven and to describe the sonographic findings that permitted the diagnosis. A 29-year-old man with multiple large keloids on the chest wall presented with a two-day pain history, increased volume, and ulceration on one side. Physical examination showed a keloid with edema, peripheral erythema, and a 1-cm central ulcer with purulent discharge. On the sonogram, multiple solid dermal hypodermal pseudotumors were visualized. The lesions were well-defined hypoechogenic heterogeneous solid masses that were hypovascular with color Doppler, concordant with keloids. Within the ulcerated enlarged mass, a complicated epidermal inclusion cyst was discovered with inflammatory changes. The significance of this case lies in the very low frequency of ulceration of a keloid and the high diagnostic value of sonography to demonstrate the presence of a coexisting epidermal inclusion cyst. In the differential diagnosis of an ulcerated keloid, sonography can assist in achieving a better presurgical approach.

Herniated superficial lipomas in gluteal and thigh support areas: a special clinical ultrasound presentation

2022 , WHITTLE, CAROLINA , FAJRE WIPE, XIMENA ELIZABETH , Catalina Silva , CASTRO MENDEZ, ALEX

Background Lipomas are the most frequent benign tumor. They have been described as soft, well-defined, slow-growing palpable masses, and classified as deep or superficial. Purpose To present the clinical and ultrasound findings of herniated superficial subcutaneous lipoma (HSL), located in pressure/support areas, not previously described. Material and Methods A seven-year retrospective review was performed. Patients with a preoperative high-resolution ultrasound (HRUS) diagnosis of HSL archived in the computational system and histological study information were selected. Results A total of 37 patients (mean age = 46 years) were recruited. The clinical diagnoses were “lipoma” or “suspected lipoma” in just 46% of the cases. This was three times more frequent in women. Tumors were located mainly in the gluteal (38%) and proximal thigh areas (35%). Clinically, all patients showed small, soft, rounded skin nodules. On HRUS, they appear as lipomatous tumors that protruded, compressed, and thinned the covering dermal layer. The subcutaneous portion was bigger than the herniated part, with an iceberg image. Conclusion HSL in support areas have a special clinical ultrasound presentation, not previously described. It is important to recognize them for a proper diagnosis and treatment, especially because they clinically may present as small superficial lesions; however, they are associated with a larger subcutaneous portion (iceberg image). It is probable that an estrogen influence on the adipose tissue can be suspected because of the female predominance.

Subgaleal lipomas. Ultrasound findings

2008-03 , WHITTLE, CAROLINA , Cortés, Marcela , Baldassare, Gina , CASTRO MENDEZ, ALEX , CABRERA MORAGA, RAUL ALEJANDRO

Lipomas are frequent benign soft tissue tumors. They are classified as superficial or deep. In the head, they are localized under the galea or epicraneal aponeurosis. Clinically they present as non symptomatic smooth tumors.
