Lung transplantation offers life-saving and life-extending treatment for children and adolescents with congenital and acquired forms of pulmonary and pulmonary vascular disease, for whom medical therapy is ineffective or insufficient for sustained response. This review summarizes the pathology related to lung transplantation for the practicing pediatric pathologist and also highlights aspects of lung transplantation unique to the pediatric population. Clinical issues related to availability of organs, candidate eligibility, surgical technique, and postoperative monitoring are discussed. Pathologic evaluation of routine surveillance transbronchial biopsies requires attention to acute cellular rejection, opportunistic infection, and other forms of acute and resolving lung injury. These findings are correlated in some cases with endobronchial biopsies and bronchoalveolar lavage as adjunctive tools in surveillance. Open or thoracoscopic biopsies also have diagnostic utility in cases with acute or chronic graft deterioration of uncertain etiology. Future challenges in pediatric lung transplantation are similar to those in the adult population, with continued efforts focused on prolonging graft survival, prevention of bronchiolitis obliterans syndrome due to chronic cellular rejection, and evaluation of humoral rejection.

Rare Phenotype

We present a case of unilateral terminal transverse forearm deficiency with subterminal digit-like nubbins, identified in a fetus from a pregnancy terminated electively in the second trimester because the distal right arm and hand could not be seen by ultrasound and were presumed to be absent. Pathologic evaluation showed distal transverse shortening, tapering to a point in the mid-forearm. Five primitive digital nubbins were present, located just proximal to the tapered point. The arm vessels appeared normal histologically, and the amnion showed no evidence of intrauterine disruption. Histologic examination of the nubbins revealed osteocartilaginous tissue, never described previously within digital nubbins. This fetus has the rare phenotype of terminal transverse limb defects with residual nubbins, but differs in that the nubbins are not at the tip of the terminal transverse limb defect.

Abstract Introduction Heterotopic ossification of large joints is a commonly seen and described entity in Burn survivors. We have observed a rather uncommon phenomenon in a series of 4 Burn survivors who presented to our Burn center for scar treatment and open wounds many years after their injuries. A chronic, small, splinter-like subcutaneous irritation led to open wounds and infections in their burn scars. A similar condition is known as dystrophic calcinosis cutis in the dermatologic literature, but caused by calcium metabolism changes in otherwise healthy skin. Methods The demographics and history of illness was documented in all 4 patients. A literature review was performed. The calcified bone-like irritant was removed surgically in all patients, sometimes in more than one location. Pathologic evaluation was performed on the removed specimen. Strategies leading to healing of the wounds were evaluated. Results Four publications were found addressing this phenomenon in Burn scars, all case reports. All of our patients had undergone curettage of the lesions by a dermatologist in the past without resolution. All lesions were excised surgically and proved to extend subcutaneously far more extensively than the visible skin lesion. X rays proved not helpful in preoperative assessment of the extent. All wounds healed after the irritant was removed. Conclusions All lesions appeared to have formed along tendon or fascia remnants underneath the burn scars, exerting pressure on the overlying epithelium which eventually led to breakdown and necrosis. This finding prompted the term “heterotopic cutaneous ossification”. Chronic tension and inflammation were assumed in the etiology, rather than calcium metabolism abnormalities or systemic connective tissue disease, which were not present in these patients. Research is needed to establish the prevalence, cause, and prevention of this condition in Burn survivors.

Abstract Context.—Frozen section of lung tissue is performed to guide the surgeon in subsequent therapy. Design.—Practical experience in frozen section of the lung was reviewed in the medical literature and from the records of several academic hospitals. Results.—Most frozen sections of the lung are performed for evaluation of a solitary nodule, a mass, or the surgical margins of a resection. Frozen section may also be used to assess the adequacy of a lung wedge biopsy taken for later diagnosis of a condition. Conclusion.—The pathologic evaluation of intraoperative pulmonary lesions is indicated for the differential diagnosis of pulmonary nodules and masses, both neoplastic and nonneoplastic, surgical resection margins, and mediastinal lymph nodes. The most worrisome pitfalls involve differentiating benign reactive atypia from malignancy on frozen section.
